By the end of 2018, Wu'an Municipal People's Government of Hebei Province issued a notice on the issuance of "blue sky Wu'an winning three-year action plan to defend the war", referring to the notification: By the end of 2019, the city has a depth of discharge conditions for reconstruction the coal-fired units completed in-depth treatment, meet the relevant standards. Implementation of coal-fired power management depth. Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, security is not up to 300,000 ten million coal-fired units.

First, the implementation of in-depth treatment of coal-fired power plant

Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. 2018, 2019, 2020, respectively, by province and Handan given task given the amount of closed down. Heating demand complete transformation of 600,000 kilowatts grade pure condensing units, high-capacity, high-parameter units accounting for 90%

on.

Special action to carry out deeper cuts power industry, coal-fired units in the original ultra-low emissions, based on the further optimization of operational management, improve pollution control facilities, improving removal efficiency, the implementation of colored smoke plume power plant management. Before the end of 2019, the city has deeper emission coal-fired units to complete the transformation of the conditions of the depth of management, meet the relevant standards.

Second, to carry out special treatment industrial furnaces

The development of industrial furnaces comprehensive remediation plan to carry out an intensive investigation of industrial furnaces, establish classification list management. Stringent emission standards, increase efforts to eliminate non-compliance of industrial furnaces, accelerate the elimination of small and medium gas furnace. Under the premise of resources to implement and encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace); out hearth diameter of 3 m or less gas furnace fuels, natural gas use conditions have temporarily , building a unified center of clean coal gas principle; prohibition blended with high-sulfur petroleum coke.

CBM has provided boiler solutions to more than 10,000 customers, and the paper industry has always been a major supplier of boilers. According to the experience of CBM's cooperation with various enterprises in the paper industry in different countries and regions for many years, most paper mills use water treatment duplex softener steam boilers. There are many kinds of CBM steam boilers, which are divided into various steam products according to the fuel structure and performance.

Low nitrogen gas boiler, as the name implies, refers to the use of natural gas as a fuel, and a series of measures, such that the major air pollutants - nitrogen oxide (referred to as NOx) emissions decreased down to within the range of emission standards. Nitrogen gas boiler low NOx generation type can be divided into thermal NOx (ThermalNOx), flash type NOx (PromptNOx) and the fuel type NOx (FuelNOx). 1, since the amount of nitrogen gas is lower, and therefore, the fuel NOx is not a major type of control. 2, thermal NOx refers to NOx combustion air at a high temperature oxidation of N2. On the thermal NOx formation mechanism commonly used in the Czech Popovich channel mechanism: When the temperature is lower than 1500 ℃, the heat generation amount of NOx is small; Above 1500 ℃, the temperature is increased 100 ℃, the reaction rate will increase 6 to 7 times. In the actual combustion process, since the temperature distribution in the combustion chamber is not uniform, if there is a local high-temperature region, the NOx generated in these areas will be more, it may be the entire NOx formation in the combustion chamber plays a key role. 3, in the case of prompt NOx in the combustion of hydrocarbon fuel and fuel-rich reaction zone quickly generate NOx. Various factors alone changes in the actual combustion process, a number of parameters are in constant flux, even a simple combustion of gaseous fuel, the fuel and air should be subjected to mixing, combustion fumes, until leaving the furnace. The degree of mixing temperature of the furnace fuel and air, flue gases in the furnace and residence time of these parameters have a great effect on NOx emissions are in constantly changing.

Henan a gas boiler operating instructions. Henan open gas-fired boiler furnace 1. Check Check Henan gas water treatment duplex softener steam boiler cylinders the steam valve (production, bathroom hot water tank), should be in the closed state 2. Check Henan gas boiler water level gauge, It should be in the L level to H scale range. Water level gauge valve should be in an open position. When dry, replenishment should manually into the L and H-scale range soft water tank 3. Check level Henan gas boiler, the water level should be in the high pressure gas 4. Check the status Henan gas boiler, 4-5Kp should be within the range, and the gas boiler Henan 5. check room Henan no gas odor gas boiler water softening equipment, should be at the "water production" state, water tanks and water production testing should be blue. 6. Check Henan gas boiler inlet valve 7 is open should check Henan gas boiler dosing bucket level, should be above the minimum dosing graduations. 8. Check Henan gas boiler control each switch box, is in the standby state two. Henan gas boiler 1. Open the power turned on, until the end of the voice prompt, the panel press "RUN" operation. 2. Check Henan gas boiler flanges and valves, no gas leak. Note 3. Henan gas boiler runtime matters: A, Henan check within the gas boiler furnace should be no abnormal sound. The flame is blue. B, when viewed Henan gas boiler feed water, the pump should be in working order. Pressure (0.2 to 0.4). C, Henan observed tonic gas boiler, a state should be in automatic infusion. D, examination Henan Burner gas, when the air pressure was raised to 0.8MP, should be in the stopped state. 4. aspirated, slowly open the main steam valve, to avoid water hammer; steam trap is to be a main valve fully open slowly. 5. When the pressure was raised to 0.4 ~ 0.8MP operating pressure, manual drain valve to open sub-cylinder, 20 seconds off. Power operation, should pay attention to the boiler operating conditions, not to leave. When the shutdown check exceeds the specified value. III. Henan normal gas boiler shutdown 1. Click on the control panel the red "STOP" button to confirm the burner stops running, personnel before leaving. 2. burner to be completely stopped, wait 30 minutes after closing the steam valve cylinder points. IV. Henan gas boiler blowdown method of operation when the water level is in the M or H level, the control panel of the pump control button to manually hit. (Note: When the water level is L, a direct discharge valve is opened).
