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. Safety knowledge; boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public companies and all walks of life, are dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses to the state and people's lives and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", the boiler should use full attention the following matters: 1, should be accompanied by safety technical specifications of the factory boiler design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision, inspection and performance certificate). 2, boiler installation, maintenance, alteration.

（9）Combustion Adjustment method of Oil-fired Gas-fired Boiler

The combustion adjustment of oil-fired gas-fired boiler is successful and the load adjustment can be carried out after turning into normal operation. At this time, the combustion situation in the furnace should be observed frequently. If the atomization of oil and gas is not good, the flame jumps, the flame hits the furnace tank, and the exhaust temperature is too high or too low, the oil pressure, oil temperature, steam volume, air pressure and steam pressure should be adjusted in time to ensure the safe and economical operation of the boiler. The oil pressure and the pressure are related to the boiler load. The adjustment of the oil pressure is realized by adjusting the pressure of the burner or the amount of oil returned. The adjustment of air pressure is achieved through the opening of the valve. When adjusting a load, enter At the same time, the air volume adjustment must be carried out synchronously to ensure the reasonable match between the oil quantity and the air volume, so as to achieve the purpose of economical operation of the boiler.
