gasb boiler China

3151, most of the hot water heating gasb boiler china how to select atmospheric pressure boiler manufacturers generally choose the company's main purpose is primarily used as a hot water heating. The choice of atmospheric heating boilers must pay attention to the choice of the manufacturer, good atmospheric heating boiler manufacturer for the late running of the boiler is a great help. For the selection of the boiler manufacturer must go through a detailed comparison. Atmospheric heating boiler manufacturers must choose to focus on corporate brand awareness, a good brand of boiler manufacturers, whether pre-or after-sale are doing is in place, so you can purchase the maximum extent possible to protect businesses in the timely installation of the boiler purchase and timely operation to protect the manufacturers. For the purchase of the boiler business conditions can be ground into the various boiler manufacturers site visits, the study results can be very intuitive compared to boiler manufacturers, this is the case, for the procurement of boilers companies choose how atmospheric heating boiler manufacturer also helpful.

Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of ​​11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired gasb boiler chinas, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.

Henan gas gasb boiler china after shutdown within 6h Why should how to do either normal cooling or emergency cooling during the first 6h gas boiler shutdown of Henan, are required to turn off all the smoke, wind and bezel door? Normal and emergency cooling Henan cooling gas boiler shutdown, in the first 6h after shutdown are identical, are required to turn off all the smoke, and air shutter door. When the difference is that the normal cooling, can be opened after shutdown 6h cited blower baffle natural ventilation, while emergency cooling, allowing 6h after shutdown and start the induced draft fan ventilation Sheung strengthening, accelerated cooling to turn on the water . The main factors restricting Henan shutdown cooling rate of gas-fired boiler, steam drum after the shutdown should not produce excessive thermal stress. Steam and water drum furnace heating and ignition boosting contrast, because external drum Henan Shutdown of the gas heat-retaining layer, the drum wall temperature drop is slower than the saturation temperature decrease rate of the steam oven and water, is an upper boiler water vapor and the lower wall of the cooling drum. Henan by gas boiler drum water wall heat transfer coefficient is large, the lower half of the drum wall temperature decreased rapidly, while the saturated steam into superheated steam at the heating drum half. Superheated steam only a very small thermal conductivity, but also because he and the steam temperature is higher than the temperature, density, and natural convection can not be saturated steam is smaller than the saturated vapor. Therefore, the heat transfer coefficient on the wall of the steam drum is small, the temperature of the upper half of the drum decreases slowly. On the drum, the lower half of bananas due to temperature difference occurs upwardly formed deformation thermal stress. When a large thermal stress is formed in the initial drum boiler shutdown Henan gas, high pressure steam drum further, the superposition of both the generated stress is large conversion. Therefore, the initial Henan gas boiler shutdown excessive thermal stress would endanger the safety of the drum. Since the size of the drum of a thermal stress, and the furnace depends on the velocity of the steam saturation temperature of water is lowered. Therefore, the most effective method of reducing thermal stress is slow drum speed drum pressure drop. Within the first 6h after shutdown, close all smoke. Wind baffle and door are the best and most simple way to prevent excessive pressure drop drum. After the gas boiler shutdown Henan 6h, due to the chimney and the furnace wall heat capacity remains the wind, cold air from the smoke, wind door, shutter and the tube through the wall, which do not leak into the furnace at a close absorb heat to become hot air It is discharged from the chimney. So, even close all the smoke, wind baffle door, drum pressure is still slowly decline. After the shutdown 6h, drum pressure has dropped to very low levels, even though the ventilation and induced draft fan started to strengthen Sheung Shui, turn on the water to accelerate cooling, thermal stress is also small drum, and the drum pressure is very low at this time due to its two translation superimposed stress were also smaller, has not pose a threat to the security of the drum.

When we buy gas gasb boiler china, often hear the latent heat recovery boiler, which was hot denitration jargon and technical personnel from the mouth, then the latent and sensible heat are what the meaning of it?
