Modular commercial gas hot water boilers

1. 20 tph wns package oil and gas boiler

WNS series gas boiler is a kind of safe and high efficiency(98%) heating equipment with full automatic control system. This series oil gas fired boiler is horizontal type package fire tube boiler with three pass structure, it has compact structure, small volume, strong load adaptability and low water quality requirement. wns package boilers adopt wet back structure, it can adapt to the high temperature, has a good sealing, increase the radiation heat transfer area and improve the heat transfer efficiency.

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.

The difference between the saturated steam and superheated steam boiler steam Free Free subject supervisor monitoring the subject steam boiler, that is, the water is briefly heated to a certain extent, the occurrence of high-temperature steam industrial boilers, users can use steam from an industrial production according to the needs of perhaps heating heating. This section steam boiler lower acquisition costs, it is also appropriate to use convenient, especially gas steam boilers and biomass steam boiler, use clean energy for incineration, low fuel cost, non-polluting cleaning. Since it is a steam boiler steam intent to obtain high-quality thermal energy equipment, it heard steaming can happen divided into two types, that is, full steam and superheated steam we now say. 1. Steam is full and full steam heating water steam we can directly obtained. Full steam pressure and temperature, the density is one to one, one atmosphere steam at a temperature that is 100 ℃. If demand higher steam temperature, steam pressure only progress on the line. 2. The superheated steam superheated steam is reheated steam on the basis of full, i.e. reheating steam abilities occur. When water is present, the superheated steam is not occurred, since the water will absorb more heat steam generation. Temperature and pressure of the superheated steam is not corresponding. . As can be seen from the above, the temperature of the steam and full steam pressure is substantially proportional to, the greater the pressure, the steam temperature will be relatively higher, since the user can conditioner according to a demand.

Ukraine industrial construction quality, customer Ukraine's current visit to our company is very interested in industrial steam boilers. Our technical staff will fast one side condensing gas steam boilers, steam pipes condensing gas boilers and other star products, from performance to the advantage of his right to the customer. Natural gas is clean, easy to use and other advantages, is to use one of Ukraine accounted for a large amount of the type of energy. Fast boiler since its inception in 1998, with great concentration R & D and manufacturing of gas clean fuel boiler, has a very extensive industry experience, and to respond positively to the pace of global environmental development for the market launch of the gas boiler is not only the thermal efficiency is very high (up to more than 108%), emissions of harmful substances is very low (less than 18 nitroxides mg / m3).
