Three kinds of ventilation combined 200 bhp 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.
How to improve the thermal oil combined 200 bhp boiler efficiency oil boiler thermal efficiency is a lot of users are taken into account, we believe that this issue is the direction of each used in the production of various types of oil boiler manufacturers have been in the study. Many users at the time of the oil furnace to operate, often in the actual production process, we found some new problems, but all the problems, the headache is higher oil boiler flue gas temperature, low thermal efficiency the phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to understand this is to meet the low-temperature characteristics of the thermal oil comes as synthetic heat transfer oil. However, the vast majority of synthetic HTF complex biphenyls, benzene derivatives of both components, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended to select customers conducting oil mineral oil products. Second, conducting oil products to meet the low temperature performance process, but also have a relatively high flash point required. In general, oil engineers suggest, low flash point not lower than the HTF opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased oil boiler heating surface of the tail, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if the oil boiler and not other low-temperature heating system heat exchanger, then the only way to improve energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in the flow rate of heat-conducting oil, oil boiler in order to ensure safe, reliable and stable work, the thermal efficiency of the boiler plant with thermal oil will be a corresponding increase.
Different meaning of the data and the oxygen content of the exhaust gas fired combined 200 bhp boiler: A boiler oil-fired boiler which, it is explained below target, because through knowledge and understanding of this kind of boiler, can broaden everyone's knowledge, and at the same time, familiar with the different boiler type, so as to achieve a comprehensive understanding of the boiler, do not miss any of which. 1. fuel boiler, 0.5 tons and 0.35mw, its meaning is the same as you? An oil boiler, and 0.5 tons 0.35mw these two parameters, which specifically refers to, and is not the same, because the former is the rated evaporation of the boiler, while the latter refers to the rated power of the boiler or the rated for heat. In addition, in the unit, the two are not the same. So, obviously, on this issue, that the answer is not the same. 2. Industrial boilers, oil-fired boiler is why the general level? In addition, the oxygen content in the exhaust gas boiler fuel, how much is more appropriate? Industrial boilers, if its use is oil-fired boiler, then, it generally is a Class B boiler, that is, the pressure of the boiler is rated at 2.5MPa or less. Oil-fired boiler exhaust gas oxygen content and, in general, is controlled within the range of 3% to 5% is appropriate. If less than 3%, the problem of incomplete combustion occurs.Free Chat
