size of 6ton boiler
Excessive moisture content in steam size of 6ton boiler steam boiler steam system of hazard in the event of excessive steam water content, will constitute a steam system damage. Steam boiler system in major damage to wet steam are: 1, water droplets suspended in the steam pipeline corrosion can drop life. Replacement pipe is not as long as the cost of materials and labor, and you want some pipeline closed for repairs, it will bring some loss of production. 2, the steam contained in the steam boiler system, water droplets can damage (corrosion of the valve seat, the valve body) the control valve, so that the effect of lost, and eventually damage the quality of the goods. 3, the steam contained in the water droplets will collect on the exterior of the heat exchange water into a thin film growth. 1mm thick film of water corresponding to 60mm of iron / steel sheet or 50mm thick copper plate heat transfer, this layer of water film to change the appearance of the heat exchange coefficient of the heat exchanger, the heating time is extended, decreased production capacity. 4, wet steam with decreased total gas heat exchange device power. Water droplets occupy valuable space means boring full steam vapor will be taken to effect heat transfer. 5, the wet steam in a steam boiler system in concealing mixture of fouling in the heat exchange outer, heat exchange will decrease power. Heat exchange outer layer scale is not the same thickness, which causes different thermal expansion, a crack will occur on the outer heat exchanger. The material is heated from the condensate mixed with leak cracks, loss soiled condensate, will bring about high costs. 6, the wet steam concealing mixture control valve and steam trap fouling, will affect the operation of the valve, to add the cost of repairs. 7, wet steam boiler system, steam heating the product mixture enters the concealing eruption of steam directly, if the product requires high hygiene standards fit, becomes contaminated waste products will not be sold. 8, some processing technology is not wet steam, wet steam will eventually affect the quality of the goods. 9, in addition to the influence of the apparent power of the heat exchange outer wet steam, wet steam concealing will constitute excess water trap and condensate recovery system overload. Traps overload will condensate back, if condensed water vapor occupies space, which will reduce production capacity of processing equipment, during this period will ultimately affect the quality of the goods. 10, water droplets in the steam, air and other gases can affect the accuracy of the flow meter measuring the flow rate. Dry steam coefficient is 0.95, the configuration of the flow measurement error of 2.6%; and boring coefficient is 8.5, the measurement error will reach 8%. Means for supplying steam flow is accurate reliable data to an operator, the production technology for the process control in the best condition and to maximize the production of power, steam and water droplets so that all can not be accurately performed.
School project uses hot water size of 6ton boiler which type is better? As China increasingly improve the ecological environment protection, air emissions requirements become more stringent, the boiler must be innovative aspects of the lower row, the major boiler manufacturers have engaged in a more environmentally clean fuel gas boiler market.
PM2.5 is frequently mentioned in recent years, and its main premise was that the formation of NOx, according to the latest research results show in Beijing, PM2.5 and NOx emissions due to the formation of more than 50% of the total proportion of PM2.5. Because of a large area of coal to gas projects in recent years, the country's use of gas-fired size of 6ton boiler more than 50 million units in the Beijing area, gas boiler emissions will soon exceed the vehicle, as the primary sources of NOx in Beijing, so Beijing EPA first proposed the strict NOx emission standards: Beijing new boiler to perform emission limit of 30 mg / standard cubic meter for boilers with high-pollution fuel combustion zone ban, the implementation of emission limit 80 mg / standard cubic meter . The standard is much higher than the European emission standards for boilers, to the world's most demanding emissions standards in Southern California to move closer to the boiler.
The daily operation of the size of 6ton boiler adjustment (regulation Part 2): In a large boiler operating parameters change in the magnitude of the situation, should be used "quick adjustment" and "over-regulation" approach, the parameters can change its trend as soon as possible, the "coarse . " Especially when handling accident, to adjust the water level, particular attention should be. Case of an accident, such as "load shedding" "boiler fire" and the like, when the level variation is very large, and because the "false impact level," the rate of change quickly, operators requires rapid response and regulating. And if the mother controls the water supply system, several furnace influence each other, plus the usual low water pressure, in case of an accident, several furnaces at the same time the water level changes, "over water" is serious, and therefore more in the "coarse" They should coordinate with each other to pass on. Avoid artificially adjusting improper expansion of the accident. E.g. "turbine load rejection" and the boiler because the water level regulating improper fire; for level adjustment improper full of water when the "boiler fire"; even when a boiler blower trip underlayer powder machine speed caused by too much air duct blockage and the like.
