industrial water tube steam boilers
220ton 95bar CFB boiler palm shell fired design technology
The plant will employ the circulating fluidized bed combustion technology which is considered the best available technology to use as it enables the plant to use a wide variety of coal, while being more tolerant with regards to fouling and slagging problems.
When we use the gas boiler cleaning and maintenance is very important that we first open the burner door in the use of gas-fired boiler, remove the rear housing panel, tighten the screws to open the rear side of the boiler clean mouth. Clean fuel gas piping with a wire brush. With a soft brush to clean the combustion chamber. Gas boiler to remove residue in the boiler, the cleaning opening is screwed on the screw, closing the burner door seal check is complete. If the boiler is installed in areas where temperatures below 0 ℃ must take the following precautions: If outside the boiler room, the room temperature drops below 15 ℃ or 18 ℃, the whole day operation of the boiler. If a long time no one in the room should be emptied of water in the boiler. You know cathodic protection of each member constituting the boiler (such as iron, copper, aluminum, etc.) of different materials. In order to prevent galvanic corrosion, cathodic protection measures must be taken. Sewage treatment boiler. The bottom of the gas-fired boiler flue gas emissions to prevent condensation. Since the flue gas is flue gas condensation (diesel or natural gas) and the flue gas temperature in the aqueous too low, water generated. A portion of the moisture is discharged from the chimney, the chimney wall is absorbed, the rest is deposited on the bottom of the chimney. Water produced by the following factors influence: flue gas temperature (efficiency 91%, the flue gas must be at a temperature of 170 ℃) where the total surface area heat chimney, chimney and chimney material. Maintenance of the burner. Gas boiler and burner maintenance, the best maintenance after steam supply. Because the products of combustion will corrode the boiler, clean up carbon deposits, therefore, not allow the products of combustion in the boiler memory stay too long.
Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of boiler welds is more guaranteed.
Ordinary boiler exhaust gas temperature higher, generally up to 150 deg.] C, while the flue gas emissions, can take away a lot of heat. Natural gas fuel used in the gas boiler containing a large amount of hydrogen element, after burning will produce large amounts of water vapor, the water vapor discharged with the flue gas while the outward, it is possible to take a lot of latent heat of vaporization.
