Tail secondary combustion flue how to deal with the phenomenon of a sharp increase in rear of the supermarket hot water atmospheric pressure water tube boiler price flue secondary combustion flue temperature location and later. 2, the furnace, the flue abrupt change in negative pressure, flue gas is not tight at the smoke, the Mars. 3, air preheater large current swing bearing housing temperature, severe Jam occurs. 4, air preheater fire alarm issue. 5, steam temperature, economizer outlet water temperature, the air temperature rises abnormally. 6, induced draft fan vanes automatically open a large, Fan current rise. 7, as the combustion side, both sides of the smoke temperature difference increases. Reason 1, through the coarse fine grinding coal, coal poor uniformity, improper adjustment of combustion, combustion of fuel is insufficient, serious mechanical incomplete combustion, and high levels of combustible ash accumulated in the back pass. 2, an oil burner or an oil poor atomization, so that unburned droplets deposited in the flue. 3, prolonged low load operation of boiler, the furnace temperature is too low or too small amount of excess air resulting in incomplete combustion of coal or oil accumulated in the tail. 4, after the shutdown of the fuel leakage into the furnace and accumulates or after shutdown and to insufficient MFT furnace purge unburnt coal or oil accumulation at the end of the tail. 5, soot blower failure, long-term put into operation is not normal. 1 process, when a slight secondary combustion, exhaust gas temperature does not rise within 20 ℃ normal smoking temperature should be checked immediately paragraphs, the combustion site and judge whether the secondary steam soot blowing. (When the exhaust gas temperature rises to 250 ℃) 2, the operation of the back pass and then generating boiler combustion boiler operation should be stopped immediately, immediately stop sending, ID fan and turn off all the smoke and steam soot blowing air damper fire. 3, if the economizer afterburning, until the storage tank level control valve blocking off without pressure, flow rate of feed pump motor start 150t / h Sheung be cooled. 4, air preheater heating surface of the secondary combustion air preheater normal operation, normal operation of the air pre-heater holder; air preheater Jam occurs, the main drive motor and the auxiliary drive motor trip, contact maintenance manual plate moving continuous air preheater rotor. Soot blowing steam into air preheater for extinguishing, into the air preheater for fire extinguishing can not be extinguished. 5, the economizer outlet water temperature close to the inlet temperature (at the economizer secondary combustion), the air preheater inlet gas temperature, exhaust gas temperature, the hot air temperature is lowered to less 80 ℃, each one hole, and the hole is no longer Mars smoke and soot blowing steam stops coming out after water or fire. Open hole inspection manhole and inspection to confirm the secondary combustion goes out, after the flue vent door open to drain water inside the smoke flue opening for ventilation air damper. 6, to be re-combustion is resolved, the flue temperature does not rise and fall when stabilized, before slow regulation of the air, smoke baffle, the necessary air cooling and purging.
Luhai Gang, president of the other fast adhere to the strategic line of innovation and upgrading, were described in detail in terms of product innovation, research and development laboratory building construction, upgrade production lines, one-stop information management, so that you fully understand the fast supermarket hot water atmospheric pressure water tube boiler price dealers in the market competition It has a brand, confidence in the next cooperation. Director of sales for the upcoming new products "Thalia T6" to explain. This is a set of premix combustion technology, wings tube condensing technology as one of the Subversive vacuum boiler, can meet various needs of users, or vacuum boiler industry will bring a new trend.
Boiler water treatment analysis of safety issues: the problem of supermarket hot water atmospheric pressure water tube boiler price water treatment is an important part of the process of the safe use of boilers in general we all know that the market is now using more coal-fired steam boiler, steam boiler fuel ratio or gas accounts for a large steam boiler most, especially in the current market share of imports of fuel gas-fired boiler in the market constantly rising, mainly due to fuel gas-fired boiler of compact, small size, high water quality requirements, at the same time, due to the oil and gas combustion temperature itself relatively high, therefore, be able to do is very important for boiler water treatment, boiler water treatment, if done well it will cause boiler fouling, corrosion, which not only wastes fuel and it can lead to blocked pipes, burst pipes and other accidents, and more there will also be scrapped boiler caused severe economic losses ***. Therefore, fuel oil and natural gas boilers must strictly check boiler water treatment problem seriously.
How to divide the bath hot water supermarket hot water atmospheric pressure water tube boiler price and selection class to the bathroom, then select the main boiler needs heating hot water boilers generally refers to the bathroom so hot water boiler, it probably belongs to the scope of civil boiler life. Jacuzzi bathtub boiler electric boiler, bath oil-fired boiler, gas boilers bath tub and coal-fired boilers. Baths annual major need for heating in winter and hot water, then bath boiler how to choose it? Selection 1, the number of choices bath of hot water boiler (1) is currently the best configuration choice 1 hot water boiler heating units, 1 hot water boiler with hot water for bathing. (2) selection of large hot water boiler with a plate heat exchanger. Classification bath hot water boiler and selection of the former large investment, but it is more economical to run, since the summer, late spring and early autumn does not require heating, so running a boiler to provide hot water for a bath. By increasing the plate heat exchanger, the latter method can be implemented with a double oven, small footprint, saving the original investment. 2, select the type of coal-fired boiler pollution. Most Chinese cities are prohibiting the installation and use of coal-fired boilers. Thus, other environmentally friendly boilers, such as oil-fired boiler, gas boilers and electric boilers, are still in the selection. Bath with a gas-fired boiler more economical than oil-fired boiler and electric boiler.
