Coal-fired heating what does environmental protection have to play beg to coal boilers derivative gas project analysis have been carrying out renovation work with the provinces and municipalities boiler, heating areas have gradually entered the ranks of the transformation, from coal to gas is one of a direction following Xiaobian take you to do a simple analysis. (1) Since the background transformation in coal-fired boiler during operation, high nitrogen oxide emissions of compounds, lower operating thermal efficiency, the actual effectiveness of lower bring the actual situation, the coal gas projects imperative. (2) the transformation of the type and price analysis for the transformation of coal boiler roughly divided into two macro-transformation methods for a local auxiliary boiler configuration, for example, combustion adjustment and transformation of machine type; the other is the removal of the new boiler reconstruction. Depending on the transformation of the standard, its transformation price is not the same. Auxiliary configure the amount of replacement level is to be replaced, the price naturally vary according to different standards, it is basically to analyze specific issues. (3) The reconstruction for the related art to enhance the current boiler, boiler manufacturers in their respective transformation technology or technology patents do a certain degree of improvement and upgrade, for example, condensation technology, technology, low nitrogen, which are object in order to ensure that the boiler after the transformation has substantial progress in terms of performance or configuration, bring substantial benefits to the relevant enterprises or institutions run. Of course, the timeliness of a coal-fired heating boilers gas heating boiler change not only consideration of the item price, technology, and services related to the transformation process, the transformation of the security dimension, it will be more concerned about the point, of course, the quality of a project is considered part of the standard.

Foshan Gaoming Liu Ling Textile Dyeing and Finishing Co., Ltd. was founded in 2007, enterprises comprehensive strength, advanced processing equipment, detection means perfect, has a complete quality assurance system, the introduction into a large number of advanced production equipment, to ensure that technical standards and products stable to improve the quality of laid a solid foundation, enjoy a high reputation in the industry. Liu Ling Gao textile company twice with my company were to buy a 20 tons of steam and a whole 10 tons of steam condensing steam what does environmental protection have to play beg to coal boiler fuel gas for the production of textile dyeing and finishing company. Fang fast with strong comprehensive strength and improve the service system to win the favor of the other side, communication from the initial to the final boiler factory-installed square fast all uphold the customer's perspective to think and observe the service concept, for the sake of clever Liu Ling textile companies according to the company's actual demand for textiles, the development of specific programs.

The reason the gas what does environmental protection have to play beg to coal boiler to replace coal-fired boilers with the improvement of economic level, gas boiler to replace the coal-fired boilers, which causes the occurrence of this phenomenon it? Following small for everyone to introduce specific: 1, coal-fired boilers generally high cost, complex structure, low thermal efficiency, work slow, operating strength, requires a lot of memory and storage of coal ash sites, and the need for coal pulverized material, curing, preventing many complicated procedures and spontaneous combustion. 2, with the popularization and development of gas industry, some coal-fired boiler to gas fired boiler, although the effect is an improvement over all aspects of coal-fired boilers, but obviously with a lot of deficiencies, from the installation of the burner into the furnace, convection bank arrangement and exhaust system must accommodate the original coal-fired boiler, so the overall effect is far better than gas-fired boiler professionally designed. 3, many coal-fired boilers because of the long time use, it has been a lot of problems in the use of effects and economic terms. 4, and with increasing heating resident population of the region, the heat load of the boiler has become a serious shortage, making a lot of resident households reach room temperature heating requirements, the inconvenience to residents. 5, taking into account safety and environmental factors we have to consider its alternatives - the development prospects of the gas boiler. These are the causes of knowledge on gas-fired boiler to replace coal-fired boilers, and you also have a lot of harvest it the same with small series? I hope this helps you make better use of gas-fired boiler.

1, should guarantee the smooth flow of flue gas, have a good fullness and should avoid dead ends and dead.

2, the burner should be provided at the height position of the center of the furnace, and the combustion space and has sufficient length. Flame should not be flushed to the wall heating surface, so as to avoid incomplete combustion gases local overheating and damage to the wall.

3, since the combustion gas in the furnace backlash, high thermal strength, exposed to the bottom of the drum in the furnace should be adiabatic process.

4, various pipes, fire tube boiler furnace wall substantially refractory brick masonry, and shield plus insulation material. In the "coal to gas" should pay attention to the tightness of the furnace wall, minimizing the original door, door checks, etc., can assemble the refractory block, prevent cold air flames wounding or excessive leakage into the furnace , affecting boiler efficiency, to see the fire hole must remain closed also should see the fire hole, heat-resistant glass viewing by fire.

5, the furnace boiler and gas than coal-fired boilers, is generally greater, there is sufficient combustion space, increase the volume of gas, does not affect the transformation of combustion conditions. If the user requests output significantly improved boiler, the furnace can be increased radiation heating surface, to remove scale and soot while the inner surface of the outer heating of the original, so that without increasing the volume of the boiler case to improve the boiler output is not a problem. Thermodynamic calculations must do in the boiler, while the smoke but also good wind resistance calculation intensity calculation.
