low emission coal boiler

Henan reasonable control of gas-fired low emission coal boiler 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.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, low emission coal boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.

Recently many of my friends to consult some "coal to gas" issue, the cost is certainly more expensive than coal-fired low emission coal boilers, but specifically how much more expensive? The count this account of how the enterprise? We've put together some information for your reference.

Ordinary gas low emission coal boiler no longer use coal, and Burning natural gas, and the chimney is not black smoke, no dust, and fuel combustion is also more fully, it seems has been very good, and also condensing gas boiler will be better than this better.
