Tianjin 4-ton condensing integrated boiler gas steam boiler manufacturer provides high-quality service

Description :

　　The exhaust temperature of ordinary boilers is relatively high, and the water vapor in it is in a superheated state and exists in a gaseous state. If the exhaust temperature is lowered enough, the water vapor in the flue gas will condense, and the latent heat of vaporization of the condensed water can be utilized.

　　A condensing boiler refers to a type of latent heat boiler that fully absorbs the waste heat and steam from the exhaust gas by condensing the water vapor in the flue gas.

　　The integrated fully condensing steam boiler is different from ordinary boilers, as its efficiency can reach its limit and the emission of harmful substances is lower.

　　Cascade utilization of exhaust waste heat to fully improve boiler efficiency;

　　Low exhaust temperature and high thermal efficiency, maximizing the efficiency of the boiler. However, the thermal efficiency of ordinary boilers cannot be achieved;

　　The majority of natural gas is methane, with water vapor accounting for over 18% of the combustion products. After burning 1 cubic meter of natural gas, 1.55 kg of water vapor can be produced;

　　In the available heat energy of boiler exhaust, the latent heat of vaporization of water vapor accounts for a large share, about 3700KJ/Nm3, which accounts for more than 10% of the low-level heat generation of natural gas.

　　The heat generated by ordinary boiler combustion is transferred to the working medium by 80-85%, with heat dissipation accounting for about 1%. Depending on the fuel, the exhaust loss can reach 20-30% of the heat generated.

　　For ordinary natural gas boilers, the heat loss carried away by water vapor accounts for 55% to 75% of the total exhaust loss.

　　Lowering the exhaust temperature of the boiler to above the dew point of water vapor can increase boiler efficiency by 2-5%. Weakly lowering the exhaust temperature below the dew point can recover the latent heat of vaporization of water vapor and increase thermal efficiency by more than 11% to 15%.
