filling bottle steam atmospheric water tube boiler
After installation and commissioning fast Boiler professional and technical personnel, two hot water filling bottle steam atmospheric water tube boilers to provide our bodies quickly into the orbit of the normal operation. Meanwhile, the design of energy-saving equipment also effectively improve the thermal efficiency of the boiler, saved us a huge amount of fuel costs. --customer feedback
Introduction condensing filling bottle steam atmospheric water tube boiler: 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.

Which is good industrial gas industrial gas steam filling bottle steam atmospheric water tube boiler steam boiler Which is better? In the production industry, many places are required to use steam, so has been the purchase of industrial production are large gas steam boiler. For the plant, the purchase of gas steam boiler must go through many contrasts, choose a good cost-effective boiler is necessary. That is for industrial gas steam boiler Which is best understood in detail. The choice must be to boiler manufacturers for comprehensive consideration of various factors, for the overall strength of the manufacturers of the manufacturers there is word of mouth are to be integrated examined. In this case, the choice of boiler manufacturers are very helpful, and this is the case. Choose a good boiler manufacturers for the enterprise, whether it is pre-or post-installation services are a great help.
