Pressure boilers Products of the non-pressure hot water boiler, also called pressure boilers, boiler usually refers to the top does not bear the water column static pressure of the heating system. That is quite an open hot water tank. Meaning pressure boiler: boiler body opening to the atmosphere. In any conditions, the boiler at the water line are zero gauge pressure boiler. Pressure boilers Model consists of three parts, connected by a hyphen between the parts. Categories: pressure hot water boiler is mainly classified by fuel can be divided into CLDR (CWDR) often piezoelectric hot water boiler, CLHS-YQ (CWNS-YQ) pressure fuel (gas) hot water boilers, pressure coal-fired hot water boilers. Model: The first part of the model by atmospheric pressure boiler code, pot-type code, combustion equipment code, the rated thermal power four sections. Boiler pressure is represented by C code example: CLSG0.35; 95/70; W12 represents a vertical pipe fixed grate boiler pressure, the rated thermal power of 0.35 mW, rated outlet water temperature was 95 deg.] C, the nominal temperature of the water inlet. 70 ℃, burning anthracite class I, a second design of the boiler. Product Structure: The overall structure of pressure boilers and boiler auxiliary equipment including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.

How to choose a 17 ton steam boiler heat exchanger? Steam boiler heat exchangers are generally divided into two categories, one is a direct contact heat exchanger, and the other is an indirect heat exchanger. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. They are used to recover flue gas heat, to achieve energy saving effect of the separation device. In general, conventional steam boiler can be increased by a simple transformation of energy-saving effects, such as increased waste heat recovery installation, which is energy-efficient steam boilers advantage. To promote energy saving is largely the cause of the country, to create more profits for the company, cost savings. Choose a good heat exchanger is one way to achieve energy efficiency goals. Direct contact heat exchanger is a steam boiler with heat recovery and a high ability to remove pollutants in flue gas, but acidic water quality, not easy to use in hot water heating boiler. The so-called indirect heat exchanger, thermal energy means that we recovered from the condensed-called flue gas. Today, more and more people choose to use the steam boiler, the proportion of the market is also increasing. Such steam boiler flue gas discharged contains a large amount of steam, by condensation and release large amounts of latent heat of vaporization. Coal-fired boiler efficiency is much higher than coal-fired boilers. This boiler has a good effect on the selection of the indirect heat exchanger.
