wns series oil or gas fire tube steam boiler

Boiler is how the classification? Press export steam parameters of how to classify? Classification of the boiler is very extensive concept from different angles have different classification, can be classified by application area, according to the export media classification, but also by the pressure of the boiler classification. If the classification parameters according to the steam outlet, then find out which parameters wns series oil or fire tube steam boiler, wherein the boiler comprises evaporation, steam pressure, steam temperature etc., and is classified according to the main points of the outlet steam pressure: low pressure boiler (P <2.5MPa ), pressure in the boiler (22.5

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.

Teach you how to properly operate a wns series oil or fire tube steam boiler: steam boiler before use to conduct the inspection of the damaged insulation, burner check to see whether the normal operation, also check to ensure that the open position of the valve is correct, check the device controlled device instrumentation and safety equipment accessories, equipment must meet the requirements. Steam boiler furnace entry point confirmation are: Open the valve before and after the oil circulation pump, oil heating flow valve opens, the liquid level in the sump reasonable mediate high position, confirmed that the gas pressure before ignition of the gas burner to the range, the power supply is normal .

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving wns series oil or fire tube steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
