The Hulun Buir City, Inner Mongolia, due to its special geographical location, well into the cold season, heating boilers put into use. Safe use of district heating boiler equipment, Hulunbeir special inspection carried out the inspection work to ensure the operation of heating boilers for the Evenki Autonomous Banner Dayan Town, tie Nihe mine, Bayan hematoxylin lofty Kong and other regions.

Inspectors checked one by one aspect of the boiler, safety accessories, ancillary equipment, water quality management and data review and so on; and the verification process in all corporate communications using the boiler should pay attention to regulatory knowledge and safety knowledge, urged business executives to issue timely corrective to ensure the safe use of heating boilers.

Brief Introduction of fuel gas-fired boilers of steam condensate heat recovery boiler flue gas volume of the component is generally 15% to 19%, oil-fired boiler flue gas water vapor content of 10% to 12%, much higher than the coal-fired boiler generating water vapor content of the flue gas 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. 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. Condensing technology as a new type of environmentally friendly energy-saving technology, its principle is not very complicated, simple summary of what is recovered by condensation equipment hidden in the flue gas and water vapor in the latent heat. In conventional boilers, 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.

2, pay attention to control pressure

The presence of gas boilers running internal pressure, these pressures is to provide sufficient power to the various production facilities, however, if the pressure in the boiler too much can lead to danger, therefore, in the course of operation of the gas boiler must observe the pressure in the boiler, if we find the pressure reaches the limit load value is necessary to take timely measures.

4, after the completion of the transformation test

Upon the completion of the transformation of the boiler, but also the need for complex tests to confirm its safety, is commonly used test methods for boiler pressure after the transformation of high-pressure test, after tested and meet the standard, be considered complete the entire transformation boilers.
