automatic wns gas fired condensing steam boiler
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.
ASME gas fired automatic wns fired condensing steam boiler for sale in ZG Boiler is with the features of low investment, high efficiency, low combustion, environment protection and so on, and it is well evaluated around the world and becoming more and more popular. ZG Boiler specializes in designing and manufacturing gas fired steam boilers for the refinery industry to ensure efficient delivery of process steam and the ASME gas fired steam boiler in oil refinery is mainly used for power generation.
Run time, and the thermal conductivity of the gas boiler gas boiler after its long run, inevitably its scale and corrosion problems in the use of the process, the main reason the gas boiler scale formation is due to the water with ingredients hardness, high temperature, high pressure continuously concentrated by evaporation. Gas boiler furnace in which it is running a series of chemical and physical reactions will occur during use will effectively form a dense and hard scale on the heating surface, which would lead directly to lower the heat exchange efficiency and due to corrosion under the scale factors, it will lead to reduced boiler water wall furnace heat absorption. The outlet temperature of the gas boiler furnace during the course of an increase, so that losses will increase in the boiler, it will be effective to reduce the heat transfer in the water wall fouling equipment, so it is very likely to cause the water-cooled wall tube wall temperature results in an increase of the thermal conductivity of scale squib gas boiler waterwall at runtime only a few tenths of a steel material, when its heating surface fouling, so that the heat transfer will be impeded, in use process in order to maintain a certain boiler output, it is necessary to raise the temperature of the fire side. During the washing process gas boiler which may be employed in an efficient and environmentally friendly non-corrosive cleaning agent for cleaning the boiler, so that the device will expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. Note that after the need for effective gas boiler furnace during ignition of smoke was observed and the temperature of the main steam temperature, the case where the pressure rise of the main steam, which is encountered after the boiler ignition temperature of tobacco will significantly increase the speed of the smoke or temperature Pianman It does not rise to the herd to immediately check the oil gun fire conditions.
As a leader in the fast side condensing gas boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback
