the fuel is biomass oil fired hot water boiler in paper factory

How to ensure the normal operation of the gas steam boiler steam boiler gas used in the process in order to ensure the proper and safe use, in the design of on improving the allocation of system protection, common protection system has five steam boilers are: water protection , pressure protection, temperature protection, flame protection, power protection self-locking, followed boiler Co., Ltd. for your details each steam boiler protection system. Gas steam boiler water level to protect the five common protection systems: steam boiler is equipped with two sets of pumps, operation and use. Boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. And also has balanced water level electrode cartridge point can accurately collect to alarm level signal or to control the pump. Common pressure protection systems protect the five gas steam boiler: steam pressure protection: When the boiler pressure exceeds the rated value, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion You can also adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Steam boilers and pressure protection as the water level, the use of multiple protection: safety valve pressure controller. Temperature protection gas steam boiler five common protection systems: temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature the fuel is biomass fired hot water boiler in paper factorys. Prevent explosion of the furnace, the fuel (gas) boiler flame protection means must be provided, is a function of combustion (including ignition, combustion or misfires when halfway off, typically within five seconds re-ignition furnace in the monitoring, within 1 second running off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds purge, automatically cut off the blower and various auxiliary power boiler stop running.) by the flame monitoring and control device component.

Furnace body Design of heating BoilerHeating boiler is a kind of heat energy equipment, which uses coal, fuel oil, gas, power and other fuels as heating source, heating water or other medium to a certain temperature through pump, valve and rely on radiator to heat the local environment to achieve the purpose of heating. The boiler structure is designed according to the normal pressure, the top of the boiler is equipped with a large air hole, the boiler works under the normal pressure, far from the explosion danger; The furnace body of the boiler is optimized by computer, the size of the boiler is optimized completely, the shape of the boiler is coordinated and beautiful. The vertical boiler of CLHS adopts the combustion mode of burners, and the fuel is burned under micro positive pressure in the furnace tank. The high temperature flue gas radiates heat transfer in the furnace tank, and then enters the pyrotechnic pipe convection. Heat exchange, and finally exhaust through the cigarette box. The smoke pipe is inserted with blocking plate, which slows the discharge rate of flue gas, strengthens the heat transfer, and ensures that the heat generated by fuel combustion heats the water of the furnace to the maximum extent, which greatly improves the thermal efficiency of the boiler. The CWNS horizontal boiler adopts the full wet back type three-way structure, the flue gas flow is long, the exhaust temperature is lowered, the full corrugated furnace tank is set up, the flame is strongly disturbed, and the heat transfer coefficient is greatly improved. It also effectively prevents the reduction of equipment life due to the hot expansion and cold shrinkage of metal. Large diameter smoke pipe and large hole bridge clearance, so that the boiler in the same time scale coating thin and easy to clean up.

50, when arranged inside the boiler room to note a safety distance, the front end of the boiler ready spacing of not less than 2/3 of the length of the furnace, and not less than 2 m; vertical boiler can be shortened; bulk boiler is not less than 4 m and does not affect the blast furnace operation and maintenance. 2, the boiler side and rear channel spacing of not less than 0.8 m, and should meet the operational and maintenance (such as replacement tube bundle cleaning, stirring the fire, etc.) requirements. 3, the top horizontal boiler headroom not less than 2 m; vertical boiler top clearance height to facilitate the operation and maintenance; headroom boiler room the other channels, should not be less than 2 meters, when the passage of time and no need to operate its headroom height of 0.7 meters. 4, the boiler room is provided for two or more boilers, the boiler the distance between adjacent not less than 1 to 1.5 times the cylinder diameter of the boiler. 5, the boiler room is generally preferred fireman operation chamber provided, on the total rated greater than or equal evaporation 4t / h steam boiler (heating or the fuel is biomass fired hot water boiler in paper factory is equal to or greater than 2.8MW) must be provided stoker operating room. Electric boiler tank may be provided in front of the boiler, and to ensure the art to fireman facing boiler water gauge, pressure gauge and other instruments during operation. 6, to the total rated evaporation 2t / h fuel gas boiler room to be provided or water spray foam fire extinguisher system, should outdoor outdoor fire hydrant, other fire-fighting equipment should also have the boiler room. 7, the fuel in the boiler room daily oil tank, the oil pump is generally not located in the boiler room, between daily oil tank, the oil pump between the application of the fire resistance of greater than 2.00h wall, the fire resistance of greater than 1.50h floor spaced from the other parts. Daily fuel tank between the boiler room and the door between the oil pump should be able to self-closing fire doors Class A, and let the oil block measures. Household upper tank return pipe to be provided, should be greater than the oil return pipe back to the oil pump. 8, an oil tank and all piping must have a reliable electrostatic grounding, the grounding resistance should not exceed 30 ohms. 9, gas boiler room boiler design should also comply with the relevant safety requirements of gas boiler room.

To further promote air pollution control tough fight, push the air quality continues to improve, according to "Zhengzhou City, the 2018 campaign of air pollution control plan" and "Chung Dong New Area, the 2018 campaign of air pollution control plan" requirements, the area to carry natural gas boiler low nitrogen renovation work, hereby notify the relevant issues as follows:

(1) before the end of September 2018, Eastern 4 tons of steam boiler and above the implementation of low-nitrogen gas engineering construction and renovation. Encourage the implementation of other gas-fired low-nitrogen transformation.

Promote the transformation of low nitrogen gas boiler according to early completion, and more reward principles, decreasing year by year funding award up mode. Before the end of June 2018 to complete the construction of low-nitrogen transformation, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 40% of equipment investment; before the end of September 2018, to complete the low nitrogen renovation project construction, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 30% of equipment investment; before the end of April 2019 to complete the project construction and renovation of low-nitrogen, nitrogen oxides Or emission concentration higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 15% of equipment investment;
