Gas-fired horozontal fired water tube steam boiler in astanas can be cleaned during cleaning using efficient and environmentally friendly non-corrosive detergents. This will cause the tube to expose the primary color of the metal and reduce the impact of dirt and bio-algal sludge. After ignition of gas-fired steam boiler, attention should be paid to observing the furnace temperature and the temperature of the main steam. With the increase of main steam pressure, the flue gas temperature of boiler is obviously increased after ignition. If the temperature does not rise, you should go to the scene immediately to inspect the oil gun fire. The scale thermal conductivity of a gas-fired steam boiler is only 1/10 of that of steel. This hinders heat transfer when it scales on a heated surface. In order to keep the boiler in use The output shall increase the temperature on the combustion side. The increase of outlet temperature of gas-fired steam boiler increases the loss of gas-fired steam boiler, and the scale on the water wall of equipment will effectively reduce the heat transfer effect, which may lead to the increase of the temperature of water wall and the burst of water wall. When a gas-fired steam boiler is in operation, a series of chemical and physical reactions will occur in the furnace. In use, it will effectively form a hard and dense scale on the heated surface, which will directly lead to its heat exchange. The reduced efficiency and corrosion due to scale will reduce the heat absorption of gas-fired boilers.
What impact have fuel moisture horozontal fired water tube steam boiler in astana? Most of the aqueous fuel when coal or heavy oil with steam atomization of entrained moisture in an amount not more than 5%, no effect on the coil and the inner shell boiler, the boiler because their materials are steel, steel are mainly: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng, with a strong antioxidant, water resistance. With more moisture, combustion performance worse, if the moisture up to 40% burn will be extinguished.
Improve the thermal efficiency of gas horozontal fired water tube steam boiler in astana, to reduce the scale of the heating surface regardless prevention, gas steam boiler after a long run, it will produce some more or less scale. Gas steam boiler in operation, the furnace will be a series of chemical and physical reactions, in use, will form a hard and dense scale on the heating surface, which will directly result in reduced heat transfer efficiency of the boiler; and by corrosive effects of scale, will lead to reduced water wall furnace heat absorption gas steam boilers, which reduces thermal efficiency, waste input costs. The need to clean up the scale there is little that the boiler is to make long-term stable operation down. Scale thermal conductivity of only one percent of the steel, once the heating surface fouling, so that the heat transfer will be impeded, during use in order to maintain a constant output of the boiler, it is necessary to increase the temperature of the fire side. The outlet temperature of the furnace gas steam boiler is increased during the process, so that it will lose gas steam boiler is increased, so that effective heat transfer will reduce the equipment fouling in the water wall, so it is very likely It can cause water wall tube wall temperature increases lead to burst pipes water wall. Cleaning the boiler becomes particularly important. Performing the cleaning process, you can use efficient, environmentally friendly and non-corrosive cleaning agent, so that the device will be exposed to the original metallic tube, reduced to fouling. Secondly, after ignition gas steam boiler, flue gas temperature of the furnace needed to observe changes and the main steam temperature; when the main steam pressure is on the rise, if the boiler ignition, the smoke temperature rise speed or does not rise significantly Pianman, immediately check the oil on fire the gun.
Recently, in Qinghai Province Jigzhi County Market Authority carried out a special inspection of boiler safety within the county, mainly in order to further strengthen the special equipment safety supervision, investigation and potential risks.
County Market Authority was held on June 8 special meeting to make arrangements for this special inspection work; the meeting, Secretary of this special inspections put forward specific requirements: Either the county government and relevant departments in accordance with the superior, all in the area to check boilers, boiler and disabled to look back, to verify the implementation of the rectification; the second is to designate a person to carry out checks to ensure that this special inspection into effect, produce results; the third is to check violations found to be severely dealt with according to law.
Subsequently, according to the spirit of the meeting, Jigzhi County Market Authority Board redoubling its efforts to carry out special inspections. 5 out of law enforcement officers were examined using 10 units. The county has been reported to stop the boiler After registering with and eleven inspection and verification. Focus on checking whether the boiler inspection, whether the registration, check whether safety accessories in place, whether fireman certificates and other issues, focusing on correct pressure boilers, waste heat and pressure tanks and other equipment as well as the use of pressure boiler overpressure operation and other illegal operations behavior, found hidden among all checks for disposal in accordance with law, to ensure the safe operation of the boiler county.
Next, the county will further increase the pressure in the boiler with supervision and do routine inspections and safety management, strengthen the use of units to pay a return visit found the problem of checks put in place to promote the use of the unit responsibility, and earnestly safeguard the life and property Safety.
