steam boiler makeup water

For some of the larger sites use area, smaller capacity gas boiler is not up to heating demand; therefore, can be designed for different volumes of gas-fired boiler with a new design concept, environmental protection and efficient image according to user needs to enter a boiler market has been widely recognized and highly valued by many customers.

Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water boiler of 2.1MW.

Industrial Boiler & Mechanical proudly sells new 3 pass firetube boilers from ZBG Boiler Company, but also has the expertise to provide on-site or in-house service and repair for 3 pass boilers from other manufacturers as well.

Standard gas boiler 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.
