Quality low nitrogen gas hot water boiler
Condensing steam boiler in order to save more fuel to improve combustion efficiency: In order to improve the combustion efficiency, saving fuel, the fuel quality should be controlled, uniform atomization burner. Non-pressure condensing steam boiler indirectly heated quality low nitrogen hot water boiler, combustor or the like. To achieve the above object, the following points should be noted: 1 to understand the combustion principle, adjusting the wind ratio of positive oil (gas), to achieve efficient combustion; 2, to maintain a good working condition of the nozzle, the nozzle is not easy too large or too small, the nozzle wear obstruction, carbon status, to ensure good atomization combustion conditions. 3, to maintain proper pressure or hydraulic, pneumatic or steam boilers, such as high or low oil pressure, and a hydraulic or pneumatic pressure is too large or too small, will affect the mixing of fuel and air uniformly. 4, to adjust the burner flame length brains spray angle size and shape of the combustion chamber with fire furnace chamber filled eye, achieve economic combustion. No black smoke, no soot, in the good sense of the coming year running.
Winter is the peak heating heating, but also prone to accidents of special equipment such as boilers. To effectively prevent and curb the occurrence of accidents, equipment thorough investigation to eliminate safety hazards, Hunan Province to carry out safety hazards investigation work in the province within the boiler, boiler equipment and punishes the security measures are not in place.
Yueyang City bearing the brunt of the provincial government in response to the call for in food, pharmaceutical processing industry, boiler equipment, pressure vessels, pipelines, etc. investigation and remediation, further investigation and security risks, strengthen supervision, which ensures safe operation of special equipment.
Zhuzhou City, the relevant departments to implement the special equipment safety responsibility, collective interviews conducted meetings, some special equipment overdue inspection or rectification in place of business risks not to be interviewed. In order to urge them to get inspection reports in order to restore operation, to ensure the safe use of special equipment. But also warned of these enterprises, if not through legal regular inspections, not only safety and production are not effectively protected, will be severely punished.
Structure and characteristics of Water Tube Boiler (double Longitudinal Tube Boiler)
The structure of the double vertical tube water tube boiler is mainly composed of upper and lower vertical tube, convection tube bundle, water wall tube, header box and down tube and other pressure-receiving components. The length of the lower drum is about half shorter than that of the upper drum. The empty space is provided with a furnace, a curved water pipe is arranged between the two drums, and a water wall tube is arranged around the furnace. The burning equipment adopts a gas/oil burner, and the tail flue has an economizer. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa). The high-temperature flue gas enters the rear convection flue from the right exit of the furnace, flows in an S shape along the two smoke-proof walls, flushes the convection tube bundle laterally, and then flows through the economizer from the left side of the furnace wall, and is discharged by the induced draft fan and the chimney.
11.Steam exiting the high pressure steam turbine is called cold reheat.
It is reheated in the re-heater and sent back to the second steam turbine. By the time the flue gas exits the boiler most of the energy in the coal will be transferred to the water in the boiler. The hot gases are cleaned up before they are sent to a stack. Feed water is generally supplied by condensed steam from the low pressure steam turbine. Large amounts of cooling water are used to condense this steam into liquid water in the condenser.
