How the economy heating stove manufacturers pulverized coal fineness determined? The means by which to adjust? How the economy heating stove manufacturers pulverized coal fineness determined? The means by which to adjust? Boiler burning pulverized coal fineness to have a significant impact. The finer the coal, coal combustion more secure, less unburned heat loss, to maintain high efficiency of the fire tube boiler parts, but the power consumption milling, metal consumption may increase, but also to advance the ignition of pulverized coal, flame furnace center reduced, it is possible to burn the burner nozzle. The more coarse pulverized coal, the milling steel consumption and power consumption is small, but the mechanical loss of incomplete combustion to increase. Thus, for a given coal and boiler plants, the presence of coal into the furnace a fineness optimum value, i.e. economic coal fineness. After milling to mechanical incomplete combustion consumption loss of the coal fineness is the minimum economic coal fineness, fineness of pulverized coal in the economy, loss of incomplete combustion boiler and milling power consumption and consumption of metal the minimum sum. Usually coal fineness can proceed from the following aspects adjustment; changing ventilation system; coarse adjustment splitter diverting baffle; changing the height of the coarse separator cone.
Corrosion causes and methods fire tube boiler parts boiler corrosion is often used in the home or small-scale industries, there will be worn at the time of its use or corrosion is inevitable, but this phenomenon is caused by loss of equipment will give, I give below describes the reasons of corrosion and methods of its corroded: common corrosion forms superheater tubes and reheater, high-temperature furnace: a, a gas side corrosion, corrosion gray matter. 2, anti-corrosion method: controlling the temperature of the furnace tube, the melting point of the condensate is skipped, deferred control the oxygen content and surface treatment selected tube control, reduce the combustion of sulfur produced. 3, dew point corrosion: SO2 gas generated by the combustion, the flue gas in combination with comfortable, and sulfuric acid produced in the condensation and corrosion of the metal in the metal surface below the dew point. 4, stress corrosion: refers to brittle cracking occurs under tensile stress while the action of the metal in the particular corrosive medium and a certain level. Second, the water-side corrosion comprising: 1, corrosion free carbon dioxide: hydrogen water acidic substance depolarization caused by corrosion. Corrosion Methods: water equipment to try to remove the CO2 and carbohydrates. 2, under deposit corrosion: the metal surface when you boiler slag or scale adhesion, severe corrosion can occur beneath it, referred to precipitate corrosion. Corrosion Method: The pH of the water in the apparatus is maintained at between 9 and 11, the metal surface of the boiler protection film is stable, does not corrode. 3, soda corrosion: the metal corrosion is a chemical vapor oxidation of iron occurs. The method of anti-corrosion: Depression evaporating section smaller inclination angle, ensure the normal circulation, for higher superheat temperature superheater, heat should be used, good corrosion resistance and the like of steel pipe. 4, DO corrosion: In the soda system, metal corrosion of the steel is prone to corrosion by dissolved oxygen. Corrosion: Water favor oxygen, increase the flow rate of water, to avoid the accumulation of oxygen in the respective area, so that uniform contact of oxygen with the metal wall to form a more uniform corrosion. Boiler is very special operating environment, temperature and pressure and corrosive substances can cause equipment corrosion conditions occur, for which we have to take the right precautions to avoid future corrosion occurs during use.
The major portion of the coal available in India is of low quality, high ash content and low calorific value. The traditional grate fuel firing systems have got limitations and are technoeconomically unviable to meet the challenges of future. Regarding there are many countries have rich coal resource so they prefer to choose coal as fuel for water tube CFBC fire tube boiler parts for their factories.
Fast fire tube boiler parts is a research and development, production and sales of high-tech enterprises, adhering to the "do professional, responsible for cleaning boiler systems integration provider" business philosophy, creating a series of excellent quality boiler equipment, such as WNS series gas (oil) boiler, SZS series of gas (oil) boilers, electric boilers and so on; second to none in the area of the National clean boiler. But we never had stalled the pace of independent research in recent years, the introduction of movable type boiler, after obtaining a favorable investment market.
