Three kinds of ventilation 2 tons of boiler costs 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.
Boiler from coal to gas is to use the original coal-fired 2 tons of boiler cost demolition transformation, Burning natural gas. Compared to gas-fired boiler coal-fired boiler, the first environmental protection, the second can. Carrying coal to gas in the process, you will find that there are different gas-fired boilers, in addition to ordinary gas boiler, as well as more energy-efficient condensing gas boiler. Ordinary gas boiler is outdated, on energy saving can also have a higher standard. Then condensing gas boilers and gas boilers ordinary What are the differences?
Fuel gas control step and the blowing process air volume of the total fuel gas steam 2 tons of boiler cost steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.
Our emphasis on increasing green, local governments also 2 tons of boiler cost operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing steam boiler. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.Free Chat
