efficient coal boilers cooking steam

3, easy

Gas-fired steam boiler in the use, operation is very convenient, so will much favored by all walks of life. Because the use of all natural gas pipeline, a sustained run without any problems. Eliminating the need to transport coal use and clean-up or stacking cinder and other tedious work.

4. Clean the reason why gas steam boiler in the market to get a high rating, but also because it is clean and not contaminated during use, and does not produce black bottom of the pot, there is no air pollution. Thus, in use, compared to other boiler is the cleanest way.

The coal fired steam efficient coal boilers cooking steam consists of two large boiler drum out of factory , up major possession including boiler body , upper steel frame and furnace wall ,lower bulk including coal bucket ,chain grate ,lower furnace wall, and internal ventilation tube. Fuel: Bituminous Coal, dry-burning coal, hard coal, ligneous coal, etc.

1.Combustion and both sides of the furnace chamber adopt membrane water-cooling wall structure. With this kind of structure, the boiler has a high heat transmission coefficient, low heat loss, good air tightness, no distortion for furnace wall and no ash leakage.

2.Furnace front and rear water wall tube extend down to the upper portion of the grate and form the front and back arch, which extends the span of arch.

3. Inverted “α” arch furnace technology makes the front arch high and short, rear arch low and long. This structure increases the burning time of the flue gas in the furnace so as to improve the combustion efficiency. Besides, the streamline shape of back arch can throw the left carbon grains from the back furnace grate into the front so that the coal is easier to get ignited. Finally, many types of coal can be applied in the boiler.

4.The length of the front and back shaft is longer than the other domestic ones, which prolongs the time of fuel combustion in the furnace and lower the carbon content in the furnace slag. Thus, the overload ability of the boiler is strengthened with the increased effect area of furnace grate.

If within the natural gas efficient coal boilers cooking steam wear how to do? Off If there is detailed examination within the natural gas boiler wear how to do? Detailed examination is the key, fuel management is equally important. According to health and time natural gas boiler, we can plan a reasonable wear health check. When using the fuel, we strictly control the particle size of coal and limestone. Should strictly control the size of the bed material. Boiler waste should be handled. Boiler slag to be treated before discharge. Natural gas boiler should be installed in the heat of use, ease of installation. Hot water pipes should not be too long. It should have a good insulating layer. Hot water output to the end of the pipe should be suitably inclined. A water supply source should be equipped with a control valve. Of emissions, natural gas boiler chimney should extend to the outside, the outlet should be higher than the boiler 1.5 to 2M. If you want to reduce the impact on water wall tube, air pressure and air volume can be adjusted appropriately, effectively reduce the wear and tear of the water wall. Check the standby time is generally down or stop. To check items include leak wear, sealing the furnace and the furnace wall of smoke. In the event of wear, the need for timely repair and welding, to ensure the normal operation of the steam boiler. In general, before the gas-fired combustion of fossil fuels need to be filled in the combustion chamber, fossil fuel and bed material and recyclable materials in air speed, strength and stiffness of the shed fully integrated. Wind bottom means upwardly within the core region. Movement of the outer annular region of downwardly along the walls of the flow of boiler water, thereby prolonging the residence time of the coal particles in the furnace. Mineral particles, large amounts of ash and flue gas contains large amounts of fly ash particles, which continue to cause rapid wear of the water wall tube, wall thickness wear thin, resulting in wear and tear.

Recently, Shaanxi Province issued a notice "issued four Battle 2019 program of work". Programs that: improve the mechanism of heating prices, heating prices reasonable development of clean, green electricity implement ultra-low emissions coal-fired power plants, a comprehensive clean canceled preferential tariff class of high energy-consuming industries unreasonable prices and other preferential policies. Off Area ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace).

According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage. Actively implement alternative heat source, deadline for shutting down the Guanzhong area below 100,000 kilowatts thermoelectric ratio does not meet the national standard or alternative heat source thermal units. Optimal operation mode cogeneration units, strictly implement the "hot set electricity."
