Burns Hospital Affiliated Hospital of Shanxi Linfen Linfen Steel is attending a hospital burns burns and other diseases. Hot water nglpgburner ng burnerlpg is essential hospital equipment heat, hot water output can provide disinfection of medical instruments and ward heating demand. With constantly improving our environmental policy, boiler correspondingly introduced more sophisticated Use. Linfen hospital burns to respond positively to the national environmental policy, decided to introduce an environmentally friendly low nitrogen gas hot water boiler. Taking into account the special circumstances of the hospital, the boiler should also have the use of safe, clean overall characteristics. Based on the above considerations, finalize the Linfen hospital with burns boiler party cooperation fast, fast is provided by one side of a gas condensing pressure hot water boiler (CWNS2.1-95 / 70-Y.Q).

Standard gas nglpgburner ng burnerlpg flue gas temperature, the abnormal temperature rise control method of treatment and a heat loss, the temperature of exhaust gas boiler 1. The state does not require a standard exhaust gas temperature, but there is a predetermined low efficiency. 2, the boiler exhaust gas at high temperature of about 120-180 degrees, the higher the exhaust gas temperature is low boiler efficiency. 3, the non-condensable exhaust gas temperature 180 degrees in the art (GB shall not less than 110 degrees) and a thermal energy conversion efficiency of the exhaust gas temperature, but also on the air coefficient and so on. Second, what factors will lead to gas-fired boiler flue gas temperature rises, there is a high gas-fired boiler flue gas temperature problems during use, gas-fired boiler flue gas temperature high will reduce the thermal efficiency of the boiler, in order to solve the exhaust gas temperature excessive problems, to understand the reasons for the high temperature exhaust gas boiler? is caused by the high temperature exhaust gas boiler does what reason? 1, the heated area ash, slagging. Heat Surface Slag cause heat deterioration, deterioration of the cooling effect of the flue gas, the exhaust gas temperature. 2, when the excess air ratio and gas boiler leakage coefficient is too large, excess air increases with the same impact. 3, gas boiler feed water temperature rises. Economizer heat transfer temperature difference decreases the exhaust gas temperature rises. 4, the fuel property. When the fuel is added water, the amount of flue gas increases, the exhaust gas temperature rises. Low volatile fuels, high ash content, so that delayed ignition, the exhaust gas temperature rises. 5, combustion and air distribution mode. Combustion air distribution mode change, the furnace may lead to shift the center of the flame, the exhaust gas temperature rises. 6, when the gas boiler furnace negative pressure is too large, the smoke quicker, increase the coefficient of air leakage, the exhaust gas temperature. 7, bottom seal gas boiler water interrupted, leakage increases and the shift of the center of the flame, the exhaust gas temperature. To understand the reasons for the high temperature exhaust gas boiler, the reason to start to solve the problem of high boiler flue gas temperature, thereby increasing the thermal efficiency of the boiler. Third, the high temperature exhaust gas boiler solution 1, see the burner power with power boiler match. Burner power is too large, the transfer of small gas flow on the line. 2, check the wind volume is too large. Adjusting the amount of the wind, the oxygen content of the combustion ratio at a reasonable gas boiler the exhaust gas temperature decreases, combustion energy. Fourth, an effective method of controlling exhaust gas heat losses of the boiler size, flue gas heat loss factors determines the size of the three: the exhaust gas temperature, excess air coefficient, and the cold air temperature. Wherein the excess air ratio of gas boiler is a major factor. Excess air ratio is too large is a large waste. A lot of cold air into the furnace, reducing the furnace temperature, combustion conditions become unstable, but also increases the flue gas volume, increased heat losses. Calculations show that when the excess air ratio is increased to 3.0 from 2.0, heat losses to 4.5%. While increasing the drum Fan burden, so power consumption increases. In order to improve the gas boiler thermal efficiency, we must pay attention to and raise awareness of the serious dangers for the high excess air ratio caused by combustion in the regulation strictly control the excess air ratio, the key to avoiding excess air furnace is reasonable with the wind and with adapted to monitor control. Monitoring means are CO2 or O2 content measurement method for measuring oxygen gas boiler is usually carried out, because the combustion of gas boiler a slight positive pressure, the seal is easy to solve the problem, the oxygen content is measured more accurately reflect the excess air coefficient values. Oxygen measurement techniques now commonly used zirconia-type oxygen analyzer constant temperature, continuous on-line measurement of the oxygen content of the flue gas. The flue gas oxygen content as a reference, the correct air-fuel ratio adjustment, a low oxygen combustion. About an effective method of controlling the size of the exhaust gas boiler heat loss, current advanced technology to automatically adjust the combustion process of oxygen combustion of PLD, followed by fine-tuning "two" that the throttle damper, to ensure normal combustion, black smoke, excess air ratio as small as possible, usually to achieve the above two points, the excess air ratio is close to the threshold. The current new generation of gas-fired boiler has been relatively safe, if you want to understand the use of gas-fired boiler, price, type and other information, please contact us.

How small and medium sized nglpgburner ng burnerlpg to adjust the temperature? Usually SMIs boiler temperature adjustment means no reduction, or only to change the level of air volume decrease means from the center of the flame gas side to achieve the purpose of adjusting the steam temperature. If the hot water boiler steam temperature drops, increasing the air blowing amount, the amount of flue gas increases, steam temperature rises; or increasing the amount of induced air, so that the chamber negative pressure increases, the center position of the flame shifting superheated steam temperature will rise . However, the boiler will adversely affect the economy. Air volume increased, the flame center will increase the exhaust gas temperature rises, increasing the heat losses; air volume is increased or decreased directly affect the quality and stability of the combustion conditions, thus affecting the thermal efficiency of the boiler. If improper operation, may also cause a fire or even turn off the furnace off. Therefore, small and medium industrial boilers should be taken to avoid sudden changes in temperature regulating air volume, reduced the adverse effects of low degree. If the vapor pressure of running hot water boiler, steam temperature exceeds a predetermined allowable value, already belongs to the accidents and dangerous area, you must take urgent measures to weaken combustion intensity, adjust the boiler load, air exhaust, severe will stop boiler run.

Gas pressure Analysis of Gas-fired Steam Boiler? The gas-fired steam nglpgburner ng burnerlpg has some related factors in the parameter of gas pressure, and it is also related to other parameters, for example, it is proportional to the evaporation of the boiler, and related to the size of the burner. Therefore, in the determination of specific values, but also depends on the actual situation, it will be decided. However, in general, gas-fired steam boilers of less than 0.5 tons, gas pressure is required for about 3000Pa, more than 1 ton of gas-fired steam boilers, gas pressure is required about 5000Pa.
