high efficiency gas hot water boiler

high efficiency gas hot water boiler

Such as boiler load increased, but also to ensure the boiler load unchanged or decreased in order to prevent pressure shall increase the amount of fuel and air supply, strengthen the burning, causing the furnace exit flue gas temperature of the flue gas volume increases and lower water temperature , temperature increase; If the oil and gas fuel is combusted in the furnace carbon black is not fully formed, into the superheater flue causing secondary combustion, but also greatly increase the superheat temperature. Reducing the temperature of the main reasons: improper adjustment of combustion, low flame center furnace; superheater area is small, or too much leakage at the furnace wall; Save water flow rising or temperature reduction; drum water level or high gas-water separator separating efficiency is lowered, the humidity of the vapor is increased; superheater tube fouling, reduced heat absorption and the like.

Select the fuel gas-fired boiler when what issues should pay attention to it? With the National Energy Bureau of Statistics figures out show that China's coal reserves are decreasing year by year, has been unable to meet our daily consumption, then the traditional coal-fired boilers will be gradually out of the market, a new type of fuel gas-fired boiler will become the new main force, then we choose the fuel gas-fired boiler when what issues should pay attention to it? Xiao Bian gave you about the advantages of the river south fast fuel gas-fired boiler is reflected in What: Henan party soon, Ltd. manufactures compact gas-fired boiler fuel, boiler and ventilation, water supply, control and auxiliary equipment are provided on a chassis as possible for customers to free up more space. The advantage of this is that while the boiler is compact but its capacity is not small, hot water and heating range is not reduced because of the small volume. Main pressure connection element Henan local fast fuel gas boiler are as follows: 1, the main fire tube boiler pressure parts: the center back to the combustion chamber, boiler shell, a tube sheet, furnace, pipe tobacco, smoke box; 2 main pressure element water tube boilers: drum (drum), the waterwall tubes, boiler bank, serpentine tube header; 3, the main pressure connection element fuel gas boiler: the main welding, also part expansion may be.

If within the natural gas boiler 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.

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
