The fields of use vary for different types of water tube boilers. CBM oil and gas water tube boiler is a double-drum type boiler with a capacity ranging from 4 to 80 tons. The szl series water tube boiler is a boiler that can adapt to a wide range of fuels. The boiler can burn a variety of biomass and coal fuels. The water-cooled wall structure can be used to control the furnace exhaust temperature by increasing or decreasing the heating area of the water-cooled wall to ensure sufficient combustion. CBM also produces circulating fluidized bed water tube boilers, corner tube boilers and so on.
Pressure boilers Products of the non-pressure factory competitive price 1 ton coal fired 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.
