Calculated gas steam boiler plant to explain your boiler heating area: Gas-fired steam boiler plant to you to explain the calculation method of gas steam boiler heating area of the boiler, which is sure to install emissions-line monitoring devices, and, should environmental protection department of the monitoring center networking, so the job. And this kind of boiler heating area, specifically, then, is to be determined according to the location of the boiler, its usage and requirements. Generally speaking, if it is 1 ton, then, it is about 7000 square meters of heating area. 4 tons of gas steam boiler, which uses induced draft fan, then, that in the selection and configuration, generally speaking, if a different motor, then, there is a different choice, but specifically, then, is there are two First, Y5-47-6C, power is 15KW / 18.5kw, grade 2 is a motor; Second Y6-41-7.1C, power is 15kw / 18.5kw, the motor is four. 10 tons of gas steam boiler, between it and the workshop is to have a safe distance, and can not be a piece design, it must be independent. Therefore, it is generally to be more than 5 meters, so the job, however, can also be separated coal field.
At the end of 2018, Yantai City, Shandong Provincial People's Government Office issued the "Yantai Blue Sky win the Battle of three-year action plan implementation details," "rules" that: in principle, to new natural gas cogeneration and gas chemical projects. Details are as follows.
Continued implementation of the total coal consumption control, by 2020, the city's total coal consumption control in less than 24.19 million tons. Developed and implemented 2018-- 2020 coal consumption reduction alternatives work, the coal consumption Yajian task decomposition implemented in urban counties. Strict control of new coal project approval, approval, filing, encourage natural gas, electricity and other clean energy alternative to coal consumption. Censorship perfect substitute for coal, improve coal reduction coefficient replace coal utilization efficiency low industry. All new, revision, and expansion projects are implemented coal coal reduction alternatives, strict implementation of alternative sources and alternative proportions.
The development of special programs, out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance, the following priority out of 300,000 kilowatts to run at least 20 years of pure condensing unit, run over 25 years and Condensate Pumping Units still can not reach ultra-low emission standards for coal-fired units. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.
Accelerate the phase-out of coal-fired facilities tea furnace built in the urban counties of the region, operating a stove, grain storage and drying equipment. The city's ban on new 35 steam tons / hour and coal-fired boilers. 65 steam tons / hour or more coal-fired boilers on the basis of complete transformation of the ultra-low emissions, with the transformation of the conditions to complete all energy saving. Out of coal-fired boilers heating pipe network coverage range. In the area where no cogeneration district heating conditions, a plurality of existing coal-fired boilers, and the like in accordance with the principle of building a large-capacity volume replacement coal-fired boilers.
The implementation of non-fossil energy doubling action plan, by 2020, non-fossil fuels in energy consumption should reach its goal provincial requirements, the city's wind power, solar power, biomass power, pumped storage power generation, nuclear power and other new energy and renewable energy power generation capacity reach 7.05 million kilowatts. Where the conditions of availability of resources, to encourage the development of biomass cogeneration county, increase renewable energy consumptive, improve social proportion of the total electricity consumption of renewable energy generation.
What is the main difference between a coal-fired boiler and a gas-fired steam boiler? Nominally, the obvious difference between a gas-fired steam boiler and a coal-fired boiler is that the fuel used is different. The former uses natural gas and the latter uses coal. I think the misgivings of many boiler users are why they should eliminate coal-fired boilers because many have already purchased and used coal-fired boilers. If they switch to gas-fired boilers, it will be a huge expense. Firstly, according to the development direction of China's ecological environment, coal-fired boilers will gradually be replaced by gas-fired boilers or other clean and environmentally friendly energy boilers, and gradually withdraw from the historical stage. Yes. The difference between coal-fired boiler and gas-fired steam boiler is very big, and the main reason for eliminating coal-fired boiler is environmental protection. From the fuel supply part, the gas-fired boiler only needs a pipe to connect to the boiler; the coal-fired boiler requires coal yard, coal (belt or man-made), coal transport, loading and unloading, storage and boiler loading process. It will produce dust, causing serious pollution to people's living environment. From the point of view of atmospheric emissions, the content of dust in natural gas is very small and can be negligible; the ash content of coal is high, and the ash content is about 10% and 30%, which will produce smoke after combustion. If dust removal facilities are reduced, pollutant emissions will be reduced. It will increase; if there are more dust removal facilities, the corresponding costs will increase, which is not a long-term solution. In addition, the sulfur content of natural gas is also very small, coal-fired boiler dust removal, desulfurization and nitrogen removal can be obtained, gas-fired boilers only need to consider the problem of nitrogen removal. From the point of view of other waste emissions, natural gas is basically free of other pollutants, especially urban gas. In the case of coal, coal yards, especially small boilers built mainly in the open air, will produce coal slurry water during the rainy season, seeping into groundwater or sinks. When entering the surface water, the burning ashes are transported to produce dust. Of course, there's a difference in other ways. Different. For small-sized boilers, gas-fired boilers are more energy-saving than coal-fired boilers, with simple equipment flow, small footprint, low operating and maintenance costs, and so on. These are the main differences between coal-fired boilers and gas-fired steam boilers, and the significance of eliminating coal-fired boilers. It can be seen that the use of gas-fired boilers is the general trend of the whole society.
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.
