Thermal efficiency measures how well a CFB boiler’s heat exchanger transfers heat from the combustion process to the water or steam in the boiler. A simple ratio expressed as a percentage, thermal efficiency is basically the input energy transferred to the water or steam heating process divided by the output energy of the combustion process.
What is the role of environmental protection play a condensing 6t boiler machine commercial estonia? 1, condensing boiler is a condensing boiler with efficient flue gas condensation waste 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. 2 ,. thermal efficiency 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.  3, economic benefits condensing boiler condensing boiler water temperature of flue gas can be recovered in the boiler and the fuel type and the number of latent heat of steam boiler water using. When the ordinary recovery boiler combustion gas without condensation, the heat efficiency of the boiler if the calculated calorific value of the fuel was 90%, the use of condensing heat recovery unit, the exhaust gas temperature down to 30 ~ 50 ℃, the thermal efficiency will be increased to about 107%. In the case where the fuel consumption is constant, the lower the heating system return, the more condensing heat recovery heat recovery, the higher the thermal efficiency of the boiler. A boiler to provide heat for the winter the water conditioning water ring, which heating hot water temperature is 25 ℃, condensing boiler using a considerable saving than the conventional hot water boiler operating costs. 1 million kcal / h boiler, for example, natural gas consumption of the conventional type boiler 126.5Nm3 / h (natural gas low heat value 8500kcal / Nm3), consumption of natural gas condensing boiler 110Nm3 / h, when the boiler is operating 10 hours a day, heating period is 100 days, then, a condensing boiler using natural gas 16500Nm3 savings per year, using natural gas meter price 1.8 yuan, an annual operating cost savings 29,700 yuan. 4, the role of environmental fuel combustion condensing boiler will produce large amounts of CO2, NOX, and small amounts of SO2, these substances into the atmosphere, causing acid rain and the greenhouse effect, damaging effects on the environment. At the same time water vapor condensing boiler flue gas is condensed, you can easily remove these harmful substances in the flue gas, therefore, use of condensing boiler also important for environmental protection.
Fuel cost is definitely a key consideration when determining the boiler fuel when any customer decides to purchase a boiler. Fuel costs include fuel acquisition costs, fuel transportation costs, fuel purchase costs, and the like. Of course, customers buy boilers, not to see which fuels are cheaper to choose, but also to consider the cost performance of the boilers.
