How to divide the bath hot water shoe industry 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.
Henan combustion control and adjust fast shoe industry pressure water tube boiler price boiler company to introduce small series with the boiler combustion control and adjustment. 1 steam boiler combustion process is the basis of all the work process of the boiler, from the safe operation of the economy, environmental protection point of view, how to properly regulate the burning furnace, saving coal consumption is the responsibility of each fireman. 2 hot water boiler combustion conditions primarily by uniformly supplying the fuel, and air distribution adjusting reasonable combustion equipment is achieved, the coordination of the three, to ensure stable combustion conditions, economy, safety. When coal and boiler load changes, will need to adjust the amount of coal feed and the amount of the wind, in order to obtain a normal combustion conditions. Indicator 3.1 normal combustion conditions 4.8.3 normal combustion means: timely fire burning strong, ash burnout. Specific requirements:. A fuel inlet from the anterior arch 0.1-0.15 m fire, gray ash ex chain at the 0.3-0.4 m burnout. B. fire bed smooth, dense and uniform flame, without flame or blown partial blackening phenomenon. C. Flame intermediate white light, two dark, the fire grate bed length representing more than 3/4 of the effective length. D. pale gray smoke or nearly colorless. In order to achieve good combustion conditions, must maintain a high furnace temperature, the temperature of the upper layer is generally burner combustion layer preferably 1100-1300 deg.] C, may be determined according to the color of the flame. Furnace temperature and flame color relationship in the following table. The outlet temperature of the furnace can also be used to determine, 29MW boiler design furnace outlet temperature of 1017 ℃, 58MW of 998 ℃. 3.3 In the case of normal combustion, the oxygen content in the flue gas is constant, the oximeter, fireman can understand the situation of excess air in the furnace, the furnace excess air is generally mechanical 1.2-1.4%, of excess air and oxygen table below. Ash 3.4 combustibles content is an important sign of good and bad conditions of the boiler combustion, which fuel, combustion equipment, and operations are closely linked, general mechanical furnace ash carbon content should be less than 10%. 3.5 water boiler operation should ensure that in the case of no condensation of the tail to minimize exhaust gas temperature, exhaust gas temperature is controlled at 110-160 ℃. Adjusting and controlling the amount of coal to a fireman who adapt to changes in load, the supply must be based on different types of coal and the various stages of the heating season, the weather trend, the thickness of the seam is determined, the general control of the thickness of 80-100mm low load, medium load control in 100-120mm, high load control in 120-160mm. 2 fireman in specifying a seam thickness, to be due to the furnace, because coal should comprehensive analysis, on balance, for the ash content, water large, large particles, high ash melting point of the coal, generally the appropriate tone thick seam, opposite seam is to tune thin. Small particles of coal or pulverized coal and a low ash melting point of the plurality coal i.e. strong bonding to a thin coal seam. Generally the 3 or the boiler when the load change is not too large, the method should not be used to adjust the thickness of the seam. Because coal seam thickness adjustment can not be effective immediately adjust the load only when a large load changes, and long-term stable operation of the boiler in the new load considering regulating coal seam thickness. 4 seam thickness can be achieved by adjusting the height of the coal and layered coal hopper shutter speed of the drum. Shutter elevation coal, coal may be added into the same hierarchical improved coal hopper drum speed may be increased into the amount of coal seam in order to obtain a proper height, the height of the shutter must coal, coal hopper drum speed stratified and chain speed adjustment of the three.
