gas fired horizontal boilers dealer
Henan fired horizontal boilers dealer manufacturers fuel gas combustion boiler features a contrast, combustion of fuel is a liquid fuel and fuel oil, its boiling point is always lower than the ignition point, so that fuel combustion is always performed in the gaseous state. Fuel oil particles atomized by the jet into the furnace after the furnace is heated by high temperature flue gas, gasification, and hydrocarbon ambient air encounters the oxygen gasification, a flame. Heat produced by combustion of oil particles pass a part of the gasification and combustion of oil particles continuously, until the burning ember. The smaller the diameter of oil particles, the faster the combustion of oil particles. Similarly, the oxygen required for combustion of oil particles can be supplied in time, the combustion of oil particles can more quickly. Therefore enhanced combustion of oil must do the following: 1, to improve quality of atomization, the oil particle diameter is reduced; 2, increasing the relative velocity of the air and oil particles; 3, reasonable air distribution. Second, the combustion gas boiler manufacturers Laid Henan boiler ignition gas with a high calorific value, large amount of air, can make the combustion gas, a large amount of air mixed therewith. No fuel combustion gas atomization process with the gasification process. Gas and air mixing mode, the flame length and flame temperature has a significant impact on the intensity of the combustion. Depending on the mixed mode, the combustion method of the boiler manufacturer Henan gas boiler can be divided into three types: 1, i.e., this method does not pre-mixed combustion diffusion combustion, but interdiffusion gas nozzle opening, and burned. Shao Shao stability advantages, the structure of appliance is simple, but the flame is longer, easy to produce incomplete combustion and carbonization of the heated area. 2, partially premixed combustion air prior to combustion such a way that the combustion of part of the air mixed in advance with the gas (primary air excess coefficient between 0.2-0.8), followed by combustion. The advantage is clear combustion flame, combustion strengthened, high thermal efficiency. However, combustion instability, and high combustible component of the control primary air requirements. The gas burner usually used such combustion. 3, i.e. flameless combustion air which has been uniformly mixed with the combustion gas prior to such gas required for combustion. Primary excess air ratio is equal to the excess air ratio for complete combustion of the fuel required to obtain oxygen from the ambient air during the combustion process. When the combustion gas and air mixture reaches the combustion zone can be completed in an instant.
About condensing fired horizontal boilers dealer: major cities are now facing a wide range of frequent haze weather body, the use of new clean energy - natural gas as a heating source distributed urban heating is very important imperative way around also it has begun to implement a large area of the "coal to gas". And environmental protection and energy conservation must be combined in order to have a long-term mechanism. Natural gas condensing boiler premix gas heating than with traditional gas boiler heating heating costs can be reduced more than 30%, while the low NOx combustion techniques premix can be reduced more than 70% of nitrogen oxide emissions for natural gas efficient use of lower emissions and provides an efficient way.
What is the excess air coefficient of fired horizontal boilers dealer and boiler professionals work? Learning and understanding of the boiler, the following is mainly to answer some specific questions, which specifically is: What is the excess air ratio boiler? Its smoke is calculated, and what about? And, What are two boilers, not within the scope of supervisory inspection? Designed boiler work, which refers to what? What are the contents of their work? So, the next immediately to give a specific answer. 1. What is the excess air ratio boiler? Its smoke is calculated, and what about? Boiler excess air ratio, for the noun words, simply, is a boiler operation, the ratio between the actual and theoretical air consumption air consumption. For different types of boilers, it is not the same. For example, oil and gas furnace is 1.1, and the fluidized bed boiler, it is 1.1 to 1.2. As for the calculation of flue gas boiler, mainly related to combustion equipment type and fuel type two.
