Henan gas china supply dan manufacture spareparts boiler batu bara condensing gas boiler 1. The working principle of the gas boiler operation principle of the gas boiler is natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the amount released by burning in a furnace, to heat water in the boiler, and which is vaporized into steam energy conversion device. Principle: water drum is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water increases with increasing pressure, the pan is sealed, in which water vapor limited expansion of the pressure generated by forming a heat power (strictly speaking, water vapor in the boiler drum is heated to the constant-pressure saturated water formed regasified) is widely used as an energy source. 2.Henan condensing gas boiler working principle condensing gas boiler is the working principle of the device through a certain heat boiler combustion flue gas emissions (typically at about 140 deg.] C) for recovery of energy, the exhaust gas temperature after recovery only about 60 ℃, so improving the thermal efficiency of about 10%, naturally it saves about 10% of the gas; while the energy recovery process, but also possible to reduce harmful emissions, reduce environmental pollution. 3. A gas boiler steam and boiler works Henan condensing gas compared to the traditional boiler, the exhaust gas temperature is generally 160 ~ 250 ℃, or even higher, such that combustion of the fuel produced when water is overheated in the flue gas with the smoke. gas losses through the chimney, the conventional heat efficiency of the boiler is generally only 85% to 91%. Henan condensing boiler and the flue gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and steam, the highest thermal efficiency of up to 109%, and therefore very energy efficient. These are the gas boilers and gas condensing boiler works in Henan, the popular terms, is the use of natural gas-fired boiler to heat the water to warm or radiator heating. The condensing gas boiler condensate using the most advanced technology, it can be recycled again using the hot flue gas, it is very energy efficient.

How to deal with the causes of water shortage in Fangkuai china supply dan manufacture spareparts boiler batu bara? (1) the causes of water shortage a, the failure of water supply regulation device or the failure of water supply automatic regulation were not discovered in time. B, water level gauge, steam flow meter or feed water flow meter is not correct, which causes the operator to misjudge and operate wrongly. C, the boiler load has plummeted. D, water pressure drop. E, boiler sewage pipe, valve leakage, excessive discharge. F, water wall, economizer tube burst or leak. (2) the phenomenon of water shortage: a, the water level in the drum is lower than the gauge. A set normal water level. B, the water level indicator is below the normal minimum water level standard, and the water level alarm signals low water level. C, superheated steam temperature rises. D, the feed water flow rate is abnormally smaller than the steam flow rate. (3) when the boiler steam pressure and feed water pressure are normal and the drum water level falls below the normal water level, the following measures shall be taken: a, Compare and flush the drum water level gauge to see if it is correct. B, water supply regulation from automatic to manual, if the automatic non-electric, can be changed to manual, and increase boiler feed water. C, if treated by the above method After that, when the water level in the drum is still low, the discharge gate of the boiler and economizer should be checked. If it is found that the economizer is damaged by a large amount of water leakage and affects the water level and water circulation, the boiler should be stopped by the dispatch. D, if measures are taken to restore the water level, the water level shall continue to fall, and when the allowable minimum water level is reached, the dispatch room shall be reported and the boiler load shall be reduced. E, if the water level continues to decrease and disappears from the drum water level gauge, the boiler unit operation shall be stopped immediately and the upper water supply to the boiler shall be prohibited. (4) due to carelessness of the operator, the water level shall disappear in the drum water level gauge. Failure to detect them in a timely manner should be dealt with in accordance with the following measures: B, when the water level appears in the drum water level meter, the boiler feed water can be increased and the water level should be restored. C, when the water level fails to appear in the drum water level gauge, the boiler shall be shut down immediately and the water intake into the boiler shall be strictly prohibited.
