3 Ton Fire Tube Coal Fired Steam Boiler

3 Ton Fire Tube Coal Fired Steam Boiler

Calculated gas 3 ton fire tube coal fired steam boiler plant to explain your boiler heating area: Gas-fired steam boiler plant to you to explain the calculation method of gas steam boiler heating area of ​​the boiler, which is sure to install emissions-line monitoring devices, and, should environmental protection department of the monitoring center networking, so the job. And this kind of boiler heating area, specifically, then, is to be determined according to the location of the boiler, its usage and requirements. Generally speaking, if it is 1 ton, then, it is about 7000 square meters of heating area. 4 tons of gas steam boiler, which uses induced draft fan, then, that in the selection and configuration, generally speaking, if a different motor, then, there is a different choice, but specifically, then, is there are two First, Y5-47-6C, power is 15KW / 18.5kw, grade 2 is a motor; Second Y6-41-7.1C, power is 15kw / 18.5kw, the motor is four. 10 tons of gas steam boiler, between it and the workshop is to have a safe distance, and can not be a piece design, it must be independent. Therefore, it is generally to be more than 5 meters, so the job, however, can also be separated coal field.

Henan combustion control and adjust fast boiler boiler company to introduce small series with the boiler combustion control and adjustment. 1 3 ton fire tube coal fired 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.

Beijing New Energy Automobile Co., Ltd. is China's first to operate independently and gain new energy automobile production qualification of new energy auto companies, mainly engaged in new energy vehicles and key parts and components research and development, production, sales and service business segments, and the layout intelligent manufacturing, energy management, smart travel, Internet +, and other strategic emerging industries. In the new energy automobile manufacturing process, and a series of paint drying processes can not do without the help of hot water boiler. Due to the company before the device has reached less than the growing production needs, the introduction of the 2017 mid-tail electric company producing heating pressure hot water boiler (CEDR0.7--95 / 70-Ⅱ).

Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, coal volatile or low calorific value. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart. How early circulating fluidized bed boiler ignition achieve the protection of reheaters? Fire causes of valve failure chemical industry regulation and Countermeasures bearing parts heat treated high boiler common defects due to low bypass the security gate and reheaters failure phenomenon and treatment of condensate pump turbine worm gear failure cause analysis and improvement measures in the pneumatic valve powder operating system instructions on how to implement.
