The reason gas 25 ton steam boiler popular what are gas steam boiler works and composition of what is? You know, friends do? The following is a gas steam boiler manufacturer's technical staff to explain, I hope for your help. Gas steam boiler is a thermal energy conversion device, which uses natural gas, LPG, city gas and other gaseous fuels as a fuel, the combustion heat released in the furnace, heating the water in the pot, and it was evaporated into steam. The gas fuel boilers (pan) of the combustion energy released continuously heat the water temperature, to produce pressurized steam, the boiling point rises with increasing pressure, the expansion seal pot, the internal pressure of the steam generated is limited to form a thermal energy (strictly speaking, the boiler steam drum by constant pressure heating of the water formed, so that saturated water evaporated) as an energy resource. Gas-fired steam boiler furnace mainly from the shell and the two bodies and ensure a accessories, auxiliary equipment instrumentation, automatic control and protection system of continuous safe operation of its composition. Gas boiler steam boiler is a boiler, with a cold crucible. Pyrotechnic gas boilers have two return tubes arranged in the left and right sides, the front of the cigarette before the folding drum. Between the drum and the lower tank, having a lower tube and a water-cooled manifold, a combustion chamber to form a frame. Top drum having a vapor separator for reducing the water vapor. Gas heating boiler body surface is a lower steam drum, the water-cooled manifold and fireworks tube. Very energy efficient in terms of gas-fired boiler. His high costs in terms of fuel costs and liquefied petroleum gas and electric boilers. Gas-fired steam boiler is a protective boiler. In use, dust and gas will damage our health. Natural gas will not have this problem. High thermal efficiency gas furnace steamer, can reach more than 90%! The key is his long life, he uses dye is very clean, it does not produce dust and soot when burned in a furnace, so his life much longer than other boilers. In the development of the boiler, he is moving in environmental protection, energy conservation and development goals.

Coal-fired boilers to gas boilers benefits and precautions With the rapid development of national energy-saving environmental protection, the traditional coal-fired boiler can not meet the needs of the times. Therefore, the coal-fired boiler biomass boiler or gas boiler has become in many boiler user's choice. Before the transformation, to understand the difference between .1 and gas boiler fired boiler. Circulating fluidized bed combustion boiler fired by coal crushing device fluidized combustion process, the coal by crushing device percutaneously into the bunker through a the spreading coal coal injecting air into the furnace; circulating ash by heating, fluidized combustion process. When the coal into a gas fuel is injected directly into the combustor for combustion. 2. Combustion of Coal is mainly composed of C, H, O, N, S, ash and moisture and other elements. Generated when coal SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from flue gas emitted into the atmosphere, pollute the environment and cause harm to humans. The main components of the exhaust gas and coke are CO and H2. The main produce CO2 and H2 post-combustion, much lower than coal-fired boiler SO2, SO3 and NOX emissions. 3. Ventilation pressurized combustion coal combustion boiler used in a combustion mode. The bottom of the combustion process through the induced draft fan with fan and completed. In the combustion of coal, it requires a lot of air. Gas under a slight positive pressure in the boiler or burner slightly negative pressure, which requires less airflow. Burner air may be pre-mixed with natural gas. 4. coal boiler control reasons, material thickness, amount of wind, the wind volume, wind and other than coal, coal-fired boiler is difficult to automatically adjust the operating parameters of the boiler according to the load. However, fewer factors gas boiler, the burner valve can be adjusted according to the size of the load, easy to implement automatic control. Coal-fired boiler to a gas boiler Notes: Main results are as follows: (1) small boiler, the coal-fired boiler to a gas boiler, i.e. the negative pressure of combustion from the original to the current combustion slight positive pressure, and must pay attention to the furnace wall structure sealing problems. Closely related (2) selection and arrangement of the burner and furnace, the degree of filling of the flame in the furnace is preferably not formed dead air, to avoid the interference of adjacent flame burners, to avoid interference from adjacent burner flame. Unburned gas - air mixture should not be in contact with a heated surface, in order to avoid incomplete combustion. Gas combustion. Gas burner arrangement disposed conduit and ducts should be considered reasonable gas pipe and duct arrangement, ease of operation, inspection and maintenance. (3) the transformation of coal-fired boilers is mechanized layered gas boiler should be removed before the arch and the arch, and the bottom heating surface increases, in place of the grate, the grate to prevent overheating. Gas Velocity (4) on heat transfer surface of the fly ash is not restricted abrasion conditions, convection heating surface heat transfer coefficient is increased, increasing the pressure in the boiler where H is unduly increased. Boiler erosion surface. At this time, the capacity of the boiler should be noted that the steam separator to ensure the quality of the steam.
