gas central heating boiler

Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired central heating boilers, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation. In the specified date (June 30, 2017) completed the small coal-fired boilers out of the task before. Up to now, Chongyang County is not a new coal-fired boilers.

It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.

Three kinds of ventilation central heating boilers often used at runtime to be continuously supplied to the boiler the combustion air required, and the resulting flue gas continuously drawn, a process called draft process of the boiler. Once the venting is stopped, the boiler will stop running; usually mechanically ventilated, i.e., by means of a pressure head generated by the fan to overcome smoke flow resistance of the duct. Mechanical ventilation currently used in the following three. A negative pressure ventilation chimney addition to using, the former also mounted chimney draft fan to overcome the resistance of all of the smoke, the air duct. This small capacity of ventilation, smoke wind resistance is not so large boiler system is more applicable. Second, while a balanced draft and induced draft fan blower mounted in the boiler smoke, air system. Port to the suction passage into the furnace from the wind (including through an air preheater, and a fuel combustion device layer) overcome the resistance of the entire duct fan; furnace outlet to the outlet stack (including a negative pressure outlet furnace, boiler slag tube after anti heating surface portions of the device and the dust removal) all by flue draft fan to overcome the resistance. This ventilation can effectively into the air, and the furnace flue boilers and all run under negative pressure, boiler room of the safety and health conditions better. If compared with negative pressure ventilation, boiler air leakage is small. Currently in heating boilers, the most balanced ventilation. Third, the only positive draft blower mounted in the boiler smoke in the air system, with its head against the resistance of all the smoke duct. Then the furnace and flue boiler are all working under pressure, and thus the furnace wall and door units are required tightly sealed to prevent leakage of flames and smoke high temperature hurt. This ventilation improves the strength of the heat of combustion furnace, boiler smaller volume equivalent capacity. By eliminating air leakage boiler furnace, flues, and improve the thermal efficiency of the boiler. Positive pressure ventilation, currently has applications in the oil and gas boilers. Boiler draft ventilation is generally balanced and positive pressure ventilation. These are the three common boiler ventilation method, in the process, to constantly add fuel, while also promptly clean up the burned ashes.

Gas oil furnace and expansion tank should pay attention to what effect the high slot: the gas oil furnace, I believe we will not feel strange, but should also have a certain degree of knowledge and understanding, if the box has been concerned about the central heating boiler site, and at the same time to carefully read the relevant article, and at the same time, to grasp their knowledge of words. So, based on this, then, we will continue this work, to promote a good learning process of the product, and so that everyone from a new harvest and inspiration. 1. Gas conducting oil conducting oil furnace exhaust port, which is typically what position the boiler on? HTF HTF furnace gas exhaust port, generally speaking, at the top of the boiler, i.e. high boiler shell. Furthermore, in this site, as well as the seat member, it is mainly used to install safety valve. Moreover, this drawing on the boiler, also will be marked out, as long as you can read drawings, you can, so can avoid making mistakes. 2. Gas expansion slot conducting oil furnace, which is in use, should pay attention to what issues? Gas expansion tank of oil furnace, the origin of their name, in part because of the boiler will heat transfer oil into the expansion slot, the expansion play a role. And this means that during erection, caution needs to be done is, it can not be damaged or broken. In addition, the oil level in the expansion tank, should be well controlled, so as to ensure the normal operation of the boiler.

Because of its advanced technology, noise-free, pollution-free, and wide range of applications, it is very popular in domestic and foreign markets. The fuel used in this kind of central heating boiler is natural gas, biogas, petroleum and other fuels. It is transported by pipeline and does not need to store fuel when used. Therefore, it is more suitable in some environments such as food factories, schools, hotels and other places than boilers such as biomass boilers. . Steam boilers can be used not only for heating, power generation, but also for the industrial steam required for the production process. For example, food factories generally use steam boilers for the processing and disinfection of raw materials. As a result, the use of steam boilers is very common. And what kind of boiler to choose, you need to consider more factors.
