Xuchang City in the recently released "2018 campaign of air pollution control plan", especially for the governance of the city's boiler was planned.

Xuchang coal-fired boiler governance objectives:

In Xuchang complete basic steam 10 t / h coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, out of a planned urban area 35 steam tons / hour and coal-fired boiler.

Coal-fired boiler subsidy:

(1) the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

(2) the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;

(3) complete Chaigai coal-fired boilers for the end of October 2020, the prize money will not give up.

Xuchang boiler out of the way:

Removal, central heating alternative, coal gas, coal to electricity, use geothermal, wind, solar, biomass with a bag filter, to burn not including clean coal, coal-water slurry, anthracite, charcoal blue, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.

Pressure fire operations and precautions Henan fast boiler's water tube oil or fired steam boiler Xiao Bian told you about the operation of steam boilers and pressure fire precautions and stainless steel high temperature magnetic pump structural characteristics 1. pressure steam boiler fire steps of (1) to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. (2) to the slag is thickened seam about 1 mm from the stop grate rotation, the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal the lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the coal-fired back, a distance. (3) the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, can be restored run. 2. Note the use of a steam boiler (1) before starting Check power supply voltage, there are unusual circumstances water, close the drain valve opens the water supply valve, check whether the pump stuck, stuck if the pump, remove the fan cover, rotation of the motor shaft to the flexible state to boot. (2) When the steam boiler maintenance or replacement of parts, turn off the power to avoid live work dangerous. (3) electronic control box, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean. (4) steam boilers in accordance with quality requirements, when using the apparatus sure to install a water softener, the water softener is not used because the boiler may cause fouling, may cause serious squib, shortening the life of the boiler. (5) Please note that when using sewage. And at least once a day with a discharge pressure of between 0.1MPa to 0.15MPa discharge may be prevented clogging of pipes, sewage should be properly connected, to guard against burns. Stainless steel high temperature magnetic pump structural features: a sliding bearing magnetic pump sliding bearing materials impregnated graphite, PTFE and engineering ceramics. Because of engineering ceramics has good heat resistance, corrosion resistance, abrasion performance, so the sliding bearing magnetic pump more use of engineering ceramics production. Because of engineering ceramics are brittle and expansion coefficient, so the bearing clearance is not too small, so as not to hold the shaft accident. Since the magnetic pump in order to lubricate sliding bearing medium conveyed, it should be used depending on the medium and conditions, making use of different materials bearing. 2. Cooling lubricating fluid flow control pump operation must be flush cooling internal friction annulus region between the sliding bearing and the magnetic rotor and the containment shell with a small amount of liquid. Coolant flow rate is typically 2-3% of the design flow of the pump, the annulus area between the inner magnetic rotor of the eddy current generated spacer bush high heat. When enough cooling lubricant or flushing holes poor, clogging, the medium will result in a temperature above the operating temperature of the permanent magnet, the inner magnetic rotor gradually loses its magnetism, the magnetic force actuator failure. When the medium is water or water-based liquid, the temperature rise can be maintained in the annulus region of 3-5 deg.] C; or when the medium is a hydrocarbon oil, allows the annulus region of the temperature was maintained at 5-8 ℃. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!

Combustion Adjustment of dual-use oil and gas boilers (Skills) boiler firing was successful, the load can be adjusted to normal operation. At this point, we should always observe the furnace combustion, if there is a bad oil and gas atomization, beating the flame, the flame hit the furnace and the exhaust gas temperature is too high or too low and so, it is timely for oil pressure, oil temperature, of steam, wind, air pressure, steam pressure hanging line adjustments to ensure safe and economic operation of the boiler. Size and load size of hydraulic, pneumatic boiler related to the oil pressure adjusted by adjusting the back pressure or fuel burner to achieve the size, by adjusting the air pressure to achieve the degree of opening of the valve. Adjust the amount of oil, air pressure adjustment load, at the same time, air volume control, must be synchronized to ensure a reasonable match of oil and the amount of wind, so as to achieve economic operation of the boiler. 1, the combustion method of determining boiler fuel gas: C02 content is determined from the flue gases and excess air ratio (1) the combustion quality (2) determines the length of the flame from the combustion quality (3) from the flame color and smoke color determination 2 is good or bad combustion, fuel combustion boiler adjustment method: the normal combustion, furnace flame stability was white orange, generally rumble, or if the flame beating abnormal sound, should adjust the fuel and air volume. If the adjusted still no improvement, it should identify the cause flameout, the measures to be taken and re-ignition.

1, the boiler ready distal 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 operation and maintenance furnace.

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.

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 hot water boiler 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, total rated evaporation is greater than 2t / h of oil, gas boiler room should be set foam fire extinguisher or water spraying systems, Outdoor proper outdoor fire hydrant, other boiler room should also have fire-fighting equipment.
