Horizontal gas Fired Steam Boiler Manufacturer
The oil and gas boiler produced by ZG boiler are generally composed of two series, wns series oil and gas boiler series, which can be produced from 1 to 20 t/h, and szs series oil and gas boilers, which can be produced from 6 to 35 t/h. Both series can produce horizontal fired steam boiler manufacturers and hot water boilers in a wide range.
Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.
Gas-fired horizontal fired steam boiler manufacturer steam boiler which has the advantage compared to ordinary? With the fog and haze over the ongoing frequent occurrence, people on the importance of protecting the environment is also a new understanding of traditional coal-fired steam boiler is also limited policy, many basically let the big cities now use coal-fired steam boilers, and many areas have begun to work coal-fired boilers, low gas and steam energy saving my company's research production of boilers, environmental protection, operating costs, welcomed by the market. Energy conservation, environmental protection relative to conventional convenience I produced gas steam boiler Gas steam boiler advantages are: 1, 0.5 tons of gas steam boiler steam from the ignition to just 2-3 minutes, while the average gas steam boiler needs more than 20 minutes. 2, gas steam boiler compact, small footprint does not need to build the boiler room. 3, and does not require government departments to deal with, because the normal water level of the water capacity of only 27 liters of gas steam boiler is not within the range of technical safety supervisory inspection of the boiler, the boiler does not need professional workers, a key to start fully automatic operation. 4, heating area, there are supporting economizer 2T, increasing the heating surface of the boiler, provide the working efficiency greatly save fuel. Low cost: Compared with the fuel gas steam boiler, electric heating steam boiler can be reduced by 30% of the fuel, a steam boiler heated area can reach 92%, coupled with a supporting economizer heat generated by the boiler can be sufficiently absorbed , significant savings in operating costs of the boiler corresponding to the call of the national energy saving, gas steam boiler new products in recent years come to the fore, not only do energy conservation, which also meets the requirements of industrial production of thermal energy, ordinary steam boiler replacement product.
