Introduction condensing power plant boiler erection agencies: condensing boiler efficiency is the use of flue gas condensation heat recovery boiler to absorb latent heat from exhaust tail and the sensible heat released by condensation of water vapor, to achieve the purpose of improving the thermal efficiency of the boiler. Thermal efficiency of the condensing boiler Analysis: conventional boiler, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated without considering the heat loss of latent heat of vaporization of fuel in the high heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat of condensation and sensible heat in the flue gas water vapor. Flue gas-fired condensing heat recovery steam boiler flue gas volume components typically produce 15% to 19%, the water vapor content of the oil-fired boiler flue gas is 10% to 12%, much higher than in coal-fired boiler water vapor content below 6%. Currently the thermal efficiency of the boiler are low calorific value calculation, although nominally higher thermal efficiency, but because of high natural gas, low calorific value difference of about 10%, the actual energy efficiency to be increased. To take full advantage of energy, reduce exhaust gas temperature, flue gas heat recovery physical, when the wall surface of the heat exchanger flue gas temperature below the dew point temperature, water vapor in the flue gas will be condensed, releases latent heat, low and high 10% calorific value difference can be effectively utilized.

The pressure hot water power plant boiler erection agencies installed in the basement or on the first floor, the hot water storage tank installed on the roof, this embodiment is similar to the boiler to the atmosphere as exhaust pipe return pipe use. Although the boiler is not subjected to the pump pressure applied to the ring, but at all times are under boiler water holding tank to provide a high static pressure, the higher the floor, the higher the static pressure of the hot water.

If used in some bathing establishments power plant boiler erection agencies, when the boiler water shortage emergency, instant evaporation of water, boiler dramatic expansion in a short time. If this is really explode up, 20 meters away could be hit brick or something like that, endanger within a radius of 10 meters.

"Fast power plant boiler erection agencies furnace designed larger, flue gas recirculation provides a reliable guarantee of space. In the burner head design of the special role of combustion, high temperature flame at the outlet of the flue gas interference, be it in the furnace again achieve full combustion cycle (inner loop). this design helps fast boiler leading domestic level in boiler technology, ultra-low nitrogen oxide, the recent large-tonnage party fast brand integrated condensing boiler successful signing in Beijing, and successfully help China build the APEC summit venue. "Fang boiler fast technical director, said.
