coal fired boilers agents in south africa
Henan reasonable control of gas-fired coal fired boilers agents in south africa flue gas oxygen content from the actual point of view, in the Henan gas boiler combustion, the oxygen content of the flue gas reasonable control, can also reduce fuel waste to a certain extent. Technology is adding a control loop combustion control system, the main function of this control loop is a variable flow rate and the ratio of the combustion air flow rate control, such a control system, also known as closed loop control system of flue gas oxygen content. By using this control system, making Henan ensure the most economical gas-fired boiler burning throughout the production process. From a practical point of view this stage, the oxygen content is more commonly used in the flue gas. Therefore, it can be said, in Henan gas boiler combustion process by adding a control loop to further improve the reasonable control of the flue gas oxygen content, this method is relatively simple technology, and have a certain economy. Flue gas oxygen content control to the actual operating status of the boiler ignited, under different operating circumstances, to rationalize the ratio of flue gas oxygen content, so that as far as possible both to meet the needs of Henan gas boiler combustion, while there reduce energy consumption. Through the above analysis, we know Henan gas boiler in the actual work process, by controlling the oxygen content of the flue gas in order to achieve energy-saving operation. As people focus on air pollution, the community calls for energy saving technology is growing. In this case, the promotion of energy-saving technologies and upgrading gas boiler, it is very urgent. The relevant state departments should proceed from the actual situation, efforts to promote coal to gas projects, the implementation of the relevant environmental protection policies as soon as possible, give full play to the advantages of gas-fired boiler in terms of energy saving, thus making a contribution to our energy conservation.
Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam coal fired boilers agents in south africa can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).
Low NOx emission combustion coal fired boilers agents in south africa 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.
Circulating Fluid Boiler has high working capacity and steam pressure than chain grate coal fired boilers agents in south africas. So, those cfb boilers are often used in larger industry sites such as power plant, oil refines, chemical industry, glass plant, bricks factory, rubber industry, etc. Coal fired cfb boiler has stable and good performance. The project of 85 ton coal fired cfb boilers to Mongolia has started in July 2014. Our consumer in Power plant from Mongolia by airport to Zhengzhou, China, visited our factory and talked with our engineers.
