10Bar Coal Fired Steam Boiler Steam Boiler In China
Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler products, in March 2017 signed a six-ton steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.
Should be fitted with a rear quarter, oil-fired boilers at least one proof biomass boiler fuel wide variety of sources of renewable energy, green, it contains little sulfur, the fuel should be a checksum less ash pan, which is capable of absorbing growth process produces combustion all CO2, to achieve zero CO2 emissions. Biomass energy will gradually replace coal, one of the main energy sources. Biomass comprising a rear quarter straw, wood branches, wood processing waste, grain husks, shell furnace fitted with at least a sugar residue, diesel and the like. Its shape and size can be divided into chips (3mm), bar (> 50mm) form three. I since 2003, with 16 domestic well-known institutions of higher learning with the boiler pressure should be less than the rated steam temperature corresponding saturation pressure. Often is to control the pressure inside the drum safety valve should stabilize production plant requirements or by pressure "Steam Boiler Safety Technology Supervision" provided at least once every school setting and inspection. Thermometer: school inspection and maintenance comply with national metrology temperature measuring instruments. After a quarter should be fitted with a checksum at least once. Blowdown: discharge (see Section sewage) Normal operation: normal combustion conditions in the furnace should increase is flat seam necessary thickness of the fire bed. Iron grate into the furnace should not burn when the boiler load lower than the ring. Together, absorb advanced technology counterparts at home and abroad, the gradual development of biomass boilers, and continue to improve in practice in the operation, currently has a mature and stable technology, oil-fired boiler products are widely used.
Factors that affect factors superheated steam temperature changes affect food factory superheated 10bar coal fired steam boiler steam boiler in china plant food temperature variation effects superheated steam boiler temperature variation food factory, 1, 2 changes, and the air volume ratio of 3 changes, burner fuel properties and 4, 6, 7, change the saturated steam temperature change and desuperheating water flow operation mode change in water temperature in the pulverizing system 5, the heating surface cleanliness variation boiler load variations. Change in fuel volatile carbon content, calorific value and the like: 1. Variations in the nature of the fuel. When the roughening coal, fuel combustion in the furnace a long time, the center of the flame increases, the steam temperature. When the fuel water is increased, the heat absorption of water evaporation furnace, the furnace temperature is lowered, the increase in humidity, but also increases the volume of the flue gas, the flue gas flow increases, reducing the superheater heat radiation, convection superheater heat absorption is increased. 2. And change the air volume ratio: when increasing the oxygen content of the furnace, the low temperature due to heat absorption of cold air, the furnace temperature is lowered, the furnace outlet temperature. At a total gas flow is constant, a change will also cause shifts air distribution steam temperature. When a low flow rate is insufficient, part of incomplete combustion of pulverized coal, the flame center is moved upward, the furnace exit gas temperature. 3, changing the operating mode of the burners and pulverizing system: operating system will result in an upper pulverizing the steam temperature is increased, the swing angle of the burner changes, the change in center of the flame, steam temperature changes.
Henan combustion control and adjust fast boiler boiler company to introduce small series with the boiler combustion control and adjustment. 1 10bar coal fired steam boiler steam boiler in china 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.
