Improve the thermal efficiency of gas fired steam boiler for power generation steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the 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 tail gas steam boiler heating surface of, 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 no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.
The main components of the boiler: boiler lot of people know, but do not always understand the boiler, even customers who have purchased the boiler is not very understanding of what are the component parts of the boiler. Today to look at a detailed analysis of boiler components which mainly consists of: 1, drum. Its role is to collection, storage, and supplementary steam feedwater purification. In water-tube boilers usually 1 to drum 2, the drum is called a steam drum (drum), referred to below water or mud drum drum. The inner drum has a uniform distribution of the feedwater tank, and the water separation means the continuous blowdown apparatus. Internal boiler drum water tube assembly and a separator and the like. The outer drum containing the main steam valve, the sub-steam valve, safety valve, air valve, water level gauge, sewage connection pipe and pressure gauges. One end of the head or top of the drum was Manhole. One end of the drum head with the open manhole bottom with periodic discharge means. In many riser and downcomer (bundle) connected to form the entire structure of the elastic member between the upper and lower drum. 2, water wall heating surface. It is disposed around the furnace radiation heating surface. Boiler tube made of φ51 × 3 ~ φ63.5 × 3.5mm in industrial boilers generally used rust, while the main heating surface of the water tube boiler. Radiation heating surface absorption of radiant heat and flame shield the furnace wall, and thus play a protective role in the furnace wall; the same time, as more endothermic, the furnace temperature can be reduced, as well as to prevent burning effect coking coal seam. 3, header. It is a collection of tubes arranged in the main element is coupled, and a dispensing action of water drawn, its location has upper header and a lower header or inlet header and the outlet header bin of. A header welded seamless steel pipe is generally greater diameter and two end caps. In recent years, some manufacturers shut spinning tube ends, substituted welded end cap, a more rational structure. 4, the convection heating surface tubes. Convection convection bank known as the drain pipe, located between the upper and lower drum, generally by a boiler φ51 × 3mm steel composition, the main heating surface of the water tube boiler. In order to sufficiently absorb heat, convection bank usually intermediate, separator trap wall consisting of a flue or turns back and forth, increasing the flow of flue gas, and smoke at high speed across tube bundles. 5, the pyrotechnic heating surface tubes. Smoke tube heating surface is the main fire tube smoke-tube boiler and a combination boilers, its role is as high temperature flue gas generated from the combustion furnace flows through the inner tube, the outer pot of water continuously on the heating tube, it gradually becomes steam (or hot water). Smoke tube is typically mounted pot shell, fixed to both ends connected to the tube plate by welding or expansion. Because of its limited number of installations of the boiler shell, plus content of the tube is easy to plug fouling, easy outer tube fouling, it is not practical for large boilers. 6, the superheater. Economizer and air preheater, which belong convection heating surface. Superheater convection superheater addition, there are radiation superheater, economizer and a preheater rest are mounted boiler backpass. Their role in the main exhaust gas temperature is further reduced, improving the thermal efficiency of the boiler.
Fuel fired steam boiler for power generation can be converted into a gas steam boilers do? Hello gas can be changed if it is horizontal (1t-4t) of fuel to be steam boiler biomass gasification boiler (transformation without changing the original structure of the boiler pressure), by applying a biomass gasification burner using pyrolysis pyrolysis and chemical oxidation, and sealed by hypoxia smolder, thermal decomposition of the biomass waste to make it work as hydrogen, carbon monoxide, methane and hydrocarbons, is a high-energy combustors for boilers or other use, saving 30-60% of fuel costs while eliminating the chimney smoke, but also greatly reduce the production of sulfur dioxide at the same time to achieve energy saving win.
