How to select energy saving, gas-fired? We have to look at or listen to illustrate the introduction of natural gas boiler technician in the procurement of natural gas boilers. Gas-fired fired tube 5tph steam boiler, the type of gas hot water boiler, gas conducting oil furnace, boiler different for different occasions. After determining the procurement of natural gas boiler models, need to understand the specific configuration of the boiler, configure the following criteria: 1, the main boiler is equipped with auxiliary equipment and what. 2, meters, valves and water boilers require careful examination to understand. 3, understand the control system of the boiler: boiler power electrical cabinets, power boiler control switchgear. 4, check the electrical control cabinet, console, the control system, the drive, a display, and other electrical equipment. 5, and riot unit boiler tank daily inspection. 6, boiler factory testing and commissioning. Clear cost price of natural gas boilers, installation cost of materials and installation of boiler worker costs, transportation costs and other parts.
Recently, the vice governor of Henan provincial government, Comrade He Jinping and his party, accompanied by the main leaders of Anyang City, to visit our company for investigation and guidance. Accompanied by the Group Chairman Mr. Lu Haiqing Luhai Gang and Mr. President, R & D Center Exhibition Hall and cleaning boilers Laboratories plain plant were overall investigation. We came to the R & D Center Exhibition Hall, the research group members have been attracted to the science of video technology products, stop listening to the president on corporate R & D, manufacturing scientific products situation report.
Low NOx emission combustion boiler technology a boiler combustion boiler hypoxic hypoxia NOX emissions from combustion is the easiest way to control. And a combustion burner system does not need to make any changes, only control air flow into the furnace in operation, pulverized coal combustion process as close to the theoretical combustion air amount. Low oxygen combustion scheme can reduce NOX emissions by 20% to 30%. The program practical application subject to conditions. Low oxygen furnace, will increase the amount of unburned carbon, and more difficult for the flame of burning coal more obvious; Further, the CO concentration is also increased so that smoke, which will cause decreased boiler efficiency. Another problem is that for certain boilers, hypoxia causes the main combustion steam or reheat steam temperature is low. The burning coal to immediately, boiler efficiency and reduce the magnitude of steam temperature and other properties to determine the appropriate control value of flue gas oxygen furnace outlet (at or economizer) the specific embodiments. Second, air staged combustion technique combustion air into a plurality of strands, it is gradually mixed and pulverized coal combustion, so you can see the local area to reduce the air-fuel ratio, and the thermal decomposition of coal in the ignition phase, due to hypoxia, and thus the nitrogen oxide generation is suppressed. Air classification may be implemented within the combustor, the boiler can be completed within. 85% of the amount of air required for complete combustion is introduced to the main burner, the main burner combustion zone is insufficient oxygen for the fuel-rich conditions. Due to insufficient amount of oxygen, the flame temperature is low, the amount of nitrogen oxides to less generation of fuel nitrogen intermediates (e.g., NCH, NH3, etc.) will therefore not be oxidized NOX. Meanwhile, it has been possible to further reducing NOX generated in a reducing atmosphere to molecular nitrogen (N2 of), as a result reduces NOX emissions. An upper portion of the top floor is provided Ge overfire air (of OFA) spout into the furnace through which about 15% of the rest of the air, to avoid the high temperature flame zone, it is also possible to burn unburned carbon particles, to complete the combustion process.
Run time, and the thermal conductivity of the gas boiler gas boiler after its long run, inevitably its scale and corrosion problems in the use of the process, the main reason the gas boiler scale formation is due to the water with ingredients hardness, high temperature, high pressure continuously concentrated by evaporation. Gas boiler furnace in which it is running a series of chemical and physical reactions will occur during use will effectively form a dense and hard scale on the heating surface, which would lead directly to lower the heat exchange efficiency and due to corrosion under the scale factors, it will lead to reduced boiler water wall furnace heat absorption. The outlet temperature of the gas boiler furnace during the course of an increase, so that losses will increase in the boiler, it will be effective to reduce the heat transfer in the water wall fouling equipment, so it is very likely to cause the water-cooled wall tube wall temperature results in an increase of the thermal conductivity of scale squib gas boiler waterwall at runtime only a few tenths of a steel material, when its heating surface fouling, so that the heat transfer will be impeded, in use process in order to maintain a certain boiler output, it is necessary to raise the temperature of the fire side. During the washing process gas boiler which may be employed in an efficient and environmentally friendly non-corrosive cleaning agent for cleaning the boiler, so that the device will expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. Note that after the need for effective gas boiler furnace during ignition of smoke was observed and the temperature of the main steam temperature, the case where the pressure rise of the main steam, which is encountered after the boiler ignition temperature of tobacco will significantly increase the speed of the smoke or temperature Pianman It does not rise to the herd to immediately check the oil gun fire conditions.Free Chat
