Shangqiu City, Henan Province in 2018 coal-fired boilers Chaigai capital subsidy policy

Shangqiu City coal-fired boilers Chaigai target

"Shangqiu City People's Government Office on the issuance of Shangqiu City in 2018 air pollution control campaign of the embodiments notice" clearly requires otherwise, the city completed the basis of 10 tons of steam / h boiler and Chaigai on coal-fired, coal-fired boiler demolition and gradually expand clean energy transformation range, guide and encourage medium-sized coal-fired boilers eliminated. Before the end of 2020, basically eliminated 35 tons of steam / h and coal-fired boilers within the scope of the urban planning area.

Shangqiu City coal-fired boiler subsidy

Shangqiu City coal-fired boiler subsidy implemented gradually decline Chaigai way.

The completion of the coal-fired boilers Chaigai before the end of October 2018, giving 60,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boilers Chaigai before the end of October 2019, giving 40,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boilers Chaigai the end of October 2020, the prize money will not give up. At the same time, it prohibited the use has been shut down, eliminated waste coal-fired boilers taking state funds.

Our Client from Russia, visited our factory, the boiler manufacturing line. Considering their snack food factory daily steam requirements and rice corn cob biomass fuel advantages, our engineer recommended 4 ton DZL series biomass boiler for him. DZL series biomass boiler, can burn coal fuel and biomass fuel together. This can save fuels costs, and enhance boiler thermal effect. Another feature is DZL series structure, the packaged boiler is easy to ship, small land occupation. We reach an agreements to delivery this boiler in 45 days after receiving the order payments. We can delivery this boiler by load or by sea into Russia. Its is a kind of chain grate boiler, running biomass fuels into its chamber by chain grate. In our company, coal and biomass boiler thermal transferring efficiency can reach 85%.

Gas-fired low pressure coal fuel steam boiler 0 7 1 6 mpa tube 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.
