At present several common boiler energy-saving technologies: usually for boiler manufacturers, it means that you are saving boiler to maximize the interests of customers, providing customers with unlimited fuel savings, the electricity consumption, water consumption and so on. But the wide range of energy-saving, does not refer to an aspect of optimization can save energy boilers, here's a look now common boiler energy-saving technologies: 1 furnace arch. Industrial boiler furnace arch is very important. Arch role is to cause the furnace hearth and the organization of the mixed gas and the radiation hot flue gas flow, ignition and combustion of the fuel in a timely manner. At present, the actual amount of industrial steam boiler with its rated load often do not match, the use of coal varies widely, but often with the design coal are quite different, so in actual use, often as necessary for the furnace arch modified to meet the needs of coals. Heteroaryl coal used by the inferior design coal, the boiler furnace exit gas temperature occurs is low (about 700 degrees), lower than 200 degrees design.

Safety rules steam boiler steam boiler production, life indispensable important equipment. Boiler room is a vital part of my unit. Steam boiler having a high temperature, high pressure characteristics in use. Such as poor management, will be an accident, causing casualties, the production interruption caused serious losses to the school and state. So each time fireman and maintenance personnel to maintain a high degree of responsibility in their work to ensure the normal operation of the boiler, strictly adhered to. A strict compliance system fireman job, to play unity, mutual help support the spirit of love. Second, improve and maintain boiler equipment, keep boiler room tidy, attention and strive to save coal, water, electricity. Third, in the boiler operation to maintain a predetermined pressure, temperature, pressure must not exceed. Pay attention to discern false water level. Bearing in mind the piping, valves and the valve opening position of the distribution status of operation. Gradually closing the valve should be open or closed on the side of the handwheel. Always pay attention to the old boiler malfunction and run accident precursor, should understand the reasons for treatment and prevention of its occurrence. When the need for urgent and emergency shutdown. Keep in mind the role of the distribution board each button, leaving no more than a total pressure during shutdown and cut off the power supply. Fourth, coal hopper raised or lowered, the lower non-coal hopper to stand, the suction air blower, fan, Java machine, near the transmission gear portion, careful attention to production safety, to prevent accidents. Fireman must stick to work, and offenders a fine deal. V. PREPARATION carefully, to prevent explosive materials hazardous materials into the furnace. Plow winter freeze to prevent collapse injured seam. Coal prevent collision, twisting, crushing, usually using a tool in order. Around six, switchboard and non-flammable metal was stacked, and against dust, attention to fire prevention. Sewage on time, clean the filter in the soot. Seven, when circumstances such as fire or electrical failure in the event of boiler operation, should take urgent measures to monitor and report immediately. Eight, to be reasonable gas, save gas, stop running, take, leak, to prevent burns. IX When the boiler room accident, failure in dealing with accidents, incidents and unclear responsibilities, fireman shall not leave the boiler room. Ten, who caused the accident, were the situation to criticism and other penalties for illegal operations. XI, each class set up a part-time security officer, the implementation of strict supervision, safety procedures, the implementation of the security staff of personal responsibility.

Gas-fired steam boiler principle gas steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and which is vaporized into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, water vapor in the boiler water is heated to a constant-pressure steam drum regasified saturated formed) is widely used as an energy source. Boiler and boiler shell consists of two main furnace and ensure accessories, ancillary equipment instrumentation, control and protection system safe and economic operation of its continuous constituted. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. The basic components of a steam boiler and a steam boiler operating principle is constituted by a series of devices can be roughly divided into two main parts and auxiliary equipment. The main components of the boiler are: 1. Furnace: fuel burn-up and ensures that the boiler outlet gas temperature to a value of convection heating surface cooled safe work; 2, economizer: utilizing the heat of the flue boiler feedwater heating, to reduce the exhaust gas temperature, fuel economy and functions. 3, the drum: the respective heating surface and joined together and the boiler water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 4, water wall: mainly radiation heating surface of the boiler, the absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 5, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion; 6, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reduced exhaust tobacco temperature, increase boiler efficiency. 7, the furnace walls: a housing to protect the boiler, since sealing and insulation. Heavy furnace wall of the small boiler may also function as a support member boiler. 8, the frame: a support member and the fixing boilers, Purple east 15:33:06 boiler auxiliary equipment are: 1, the wind equipment: induced draft fan and chimney via the flue gas generated in boiler operation sent to the atmosphere. 2, dust removal equipment: removing fly ash in the boiler flue gas. 3, the fuel supply equipment: fuel storage and transportation functions. 4, water supply equipment: water pump water supply through the water into the boiler by the processing device to. 5. Dust Cleaner equipment: removing ash from the boiler and carried away. 6, the blower device: by the air blower after exports the furnace air preheater and a coal grinding device heating applications. 7, the automatic control device: automatic detection, process control, automatic protection and automatic adjustment. IMPORTANT boiler maintenance and a maintenance, water maintenance method 1. The boiler must be a qualified treatment, which is to extend the life of the boiler, ensure the safe operation of the gas and steam. 2. The water temperature should be close to the furnace temperature, preferably above 20 ℃. 3. The need for low-water cutoff periodically inspect maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. 4. require periodic blowdown operation, daily (per shift) at least once, after the sewage drain valve should be checked whether the influence by dirt and leaks; if it must be excluded. 5. Shutdown the steam pressure is not maintained, the boiler will produce steam space negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened. 6. smoke tube fouling will lead to increased exhaust gas temperature, so that boiler efficiency is lowered, so that the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling.

It is reported that the atmosphere and do in Hebei Province recently issued issued a "coal-fired boiler upgrade Hebei three-year battle plan" (hereinafter referred to as "Plan"). "Plan" put forward, will continue to increase efforts to eliminate 35 tons of steam / hour and coal-fired boilers, as of 2020, the province's 35 steam tons / hour and the boiler "No Coal", while steaming retains 35 t / h coal-fired boiler and above the implementation of energy efficiency retrofits to mention environmental protection.

2017, Hebei cities (including Dingzhou, Xinji) built-up area for 35 steam tons / hour and coal-fired boilers, the county seat 10 steam tons / hour and coal-fired boilers basically completed "clear" work. 2018, the province plans to phase out a total of 6764 units 13466 tons of steam coal-fired boiler, stove and stove operating a small coal stove, have been eliminated as of September 35 steam tons / hour and coal-fired boilers 6141 Taiwan 12485 tons of steam.

Next, Hebei will focus on the implementation of nine key tasks:

First, actively promote central heating facilities, industrial parks and accelerate the elimination of coal-fired heating boilers, the implementation of "the big-generation small" and "a garden a furnace" governance program, organized industrial wasteheat special action.

Second, increase clean energy alternatives, optimize energy structure boiler. As of 2020, municipalities and districts and counties built-up area of ​​straight pipe central heating and clean energy heating rate of 100%.

Third, increase the coal-fired boiler energy conservation and environmental protection to enhance the transformation efforts.

Fourth, increased pollutant emissions and coal quality management and control efforts, deepening the boiler control. For reservations of 35 steam tons / hour or more coal-fired boiler to install air pollution automatic monitoring facilities and networking with the provincial and municipal environmental protection department.

Fifth, to accelerate the application of new energy technologies, promote demonstration projects mature. Require municipalities to develop clean energy development plan, and carry out the heating boiler can too + + PV, geothermal pilot, accelerating wind power demonstration heating Zhangjiakou region, to promote biomass energy, gas, alcohol-based fuel, industrial waste heat, light hydrocarbon fuel and other types of energy.

Sixth, give prominence to coal-fired boilers "Gas", "electricity" management. Municipalities To plan, implementation of the "gas will change," "power given to change." Heating boilers complete transformation of all time ahead of the end of August, without access to gas, clean energy power light before shifting coal-fired heating boilers can not be removed.

Seven, to carry out comprehensive environmental remediation coal-fired boilers, the implementation of grid management systems.

Eight new boiler strict access, strict implementation of pollutants and reduce the amount of times the coal alternative system. By the end of 2018, the province's coal-fired boiler control in less than 110,000 tons of steam.

Nine, strict boiler exclusion criteria, norms and acceptance transformation.
