boiler a gas alta presso industrial
The difference between ordinary and low nitrogen boiler a alta presso industrial boiler:? With vigorously promote environmental protection department of China's low-nitrogen boiler being applied more and more common. In the eyes of many low nitrogen boiler just meet environmental protection to reduce emissions, but in reality not. The following describes a low nitrogen boiler manufacturers to distinguish the conventional type boiler and low boiler nitrogen for everyone? A difference in emissions due to the different combustion grate firing, combustion chamber, circulating fluidized bed boiler, the furnace of different structure, but also its original NOx emissions when large differences, in general, not specifically for low NOX combustion furnace using technology, circulating fluidized bed original low NOx emissions, NOx raw emission Stoker furnace represented by a chain slightly lower, industrial pulverized coal boiler as burning boiler room, the higher the NOx emissions original, well-known domestic boilers have low nitrogen emissions is greatly reduced. Second, different boiler technology, layer combustion, combustion chamber, circulating fluidized bed boiler may be different with different low NOx combustion technique in accordance with the combustion mode, the combustion boiler for the air distribution layers using an air classifier, and more often to achieve low flue gas recirculation nitrogen combustion; under the influence of a typical flue gas recirculation combustion boiler combustion zone layer, in conjunction with the air fractionation techniques for reducing NOx by catalytic char; super reduction furnace denitration technology in recent years, new furnace denitration techniques, by position reasonable combustion flame spray region ammonia, direct denitration at a high temperature flame. Low Nitrogen mainly the secondary air boiler, the coal to the location and distribution of optimal adjustment of the mouth, or the like to increase the flue gas recirculation system. Third, different security, the center layer after combustion, combustion chamber, low-NOx combustion furnace circulating fluidized bed boiler technology a large number of tests performed, it has been verified in engineering applications, in general, a low nitrogen boiler, security to be higher, the reason for its sales in recent years more and more, there are many users because of its high security, a threat to the space environment small purchase, which is one of its important differences with ordinary boilers.
Boiler installation of "blast doors," What is the role now on the market most of the boiler a alta presso industrials to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.
There are several series of oil and gas boiler a alta presso industrials produced by ZG boiler.
1.wns series oil and gas boiler
Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the boiler a alta presso industrial is supplied special sea oil processing technology company Shunde indispensable less equipment. As environmental policy progresses, the chemical industry as more polluting industries are highly valued the various departments of quality supervision, sea Shunde companies to follow the development of the State Environmental Protection pace, choose clean the boiler industry-leading fast Boiler cooperation with the parties by quickly assess the specific needs on-site estimates and sea Shunde, to provide a SZS series of 25 tons of steam water tube steam boiler (SZS25-2.0-YQ).
