natural gas hot water boiler for hotel
Compared with the coal fired boiler, natural gas fired boiler for sale in ZG Boiler has high efficiency, low combustion and less pollution, and it is convenient to install, environmentally friendly as well as energy-saving. Natural gas fired boiler can be divides into two types according to its output, one is gas fired hot water boiler for hotel, which is usually applied in daily life; and the other is the gas fired steam boiler, which is mainly applied in industrial production. Both of them can take city gas, biogas, natural gas and other gas as its fuels.
Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of 38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original boiler equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler for hotel. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
How to start running hot water boiler for hotel? When the exhaust valve is completely steam drum, main power start-up burner, and check off the boiler inlet, and a valve hole flange hand, when the air pressure rises to 0.05 ~ 0.1Mpa, add water, sewer, water supply system check experiment and sewer facilities. Hot water boiler boiler assembly PC-style controller, all functions are stored on a smart chip, intelligent boiler, digitization, automation, humane, intelligent control of boiler water temperature, water temperature reached the heating automatically stop; large screen fonts display temperature, boiler water temperature at a glance. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. When flush water gauge pressure rises to 0.1 ~ 0.15MPa, flushing water gauge pressure rises to bend 0.3MPa, fire load / small fire knob is rotated in the direction of fire. When the combustion pressure strengthened, the operating pressure is increased to 2? 3, starts to supply gas heating pipe, the water discharge valve is completely closed when the hammer, slowly open the main steam valve, to prevent water hammer is discharged from steam discharge valve, the main valve is closed after the air the main air valve was slowly opened to the full, and then inverted semicircular burner control knob active level adjustment, according to a load level adjustment (to manually start and stop the pump), at low load and high load level should be slightly higher than the normal level, slightly below the normal level of water vapor pressure adjustment: adjusting the combustion load in accordance with (manual adjustment fire / small fire) determining combustion, the combustion is adjusted to the best condition.
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.
