Introduction condensing 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.

How to operate properly pressurized gas boiler: boiler widely used in various industries basic necessities of life, as a pressured gas-fired boilers and high-pressure high-temperature thermal energy equipment, but it is a wider application of special equipment. If you do not pay attention when in use, taking the wrong method of operation, can easily cause the risk of equipment damage accident occurred. How to properly operate the gas pressure boiler, many users are very confused, fast Boiler learn how to take everyone on the proper use of the device.

Employees to the annual meeting full of plans for our programs are presented shine. Whether sporty side fast version of "Desert Camel" was full of rhythmic Allegro "golden rice bowl", it combines the efforts and achievements we have made in 2018, exceptionally exciting. There festive set in one of the nation's lasting appeal of traditional dance "dance together" and "unforgettable beauty heart", gives us the beauty of the impact.

How to use natural gas boiler to save natural gas effectivelyWe must all know that natural gas should be used in the use of natural gas, and natural gas is a non-renewable resource. How to use the natural gas boiler correctly in order to reduce the operating cost of users greatly? In use, attention to these details can reduce the use of natural gas. 1. When in use, the indoor temperature controller can be externally connected to achieve personalized temperature regulation and energy saving. According to statistics, the use of the indoor temperature controller can save 20% / 28% of the gas cost. Setting the water temperature to a constant temperature can save natural gas, such as setting the water temperature between 35 ℃ and 40 ℃. 3. Try to turn it off. Do not always turn on a gas-fired boiler for heating in the infrequent bedroom. Because hot water dissipates slowly, it can heat water intermittently. For example, it can burn for three or four hours in the morning, and then turn it off. The indoor temperature can last for a few hours. Burn for a few hours by 3: 4 p. M., turn it off when you go to bed, and keep the room warm until morning.
