It is reported that in March 15, Chifeng City, a special inspection of the pressure to carry out an internal inspection of industrial gas and steam boiler upgrade skills than the ability to test cum activity. Chifeng City, the special prosecutor, deputy director Jiao Wenxiang, deputy chief engineer Wang Shusen, deputy chief engineer Zhang Yulin and a pressure test of all personnel to participate. The ratio of the activity is divided into document review, site inspection, inquiry exchange three links, the city of Chifeng hotel comparison site inspection in WNS4-1.25-Q type of boiler.
In the field, compared to persons in accordance with the "boiler periodic inspection rules," "Boiler Safety Technology Supervision" and other relevant standards, test preparation equipment industrial gas steam boiler inspection, the document review, site inspection programs, projects, methods, inspection found defect assessment and treatment, inspection records and test the views of notice to fill in field operations and other aspects of comparison. Then the referee group of inspectors to participate in the comprehensive assessment ratio, the final nine inspectors compared the results were satisfactory. The ratio of inspectors to participate have said, by building a mutual learning platform for the exchange ratio of activities to enhance their own inspection techniques, in order to better carry out the annual inspection lay a solid foundation.
After comparison, the assessment team for each ratio of staff present in the actual operation problems raised rectification, so that each person than to recognize their lack of inspection in the presence of, as well as their ability to enhance the tailored inspection Program. In the future, I will continue to strengthen and enhance the inspection capabilities, adhere to the bottom line of thinking and problem-oriented, to provide a solid technical support for the safety of special equipment to hold the bottom line.
Check the work before the start fuel gas-fired boiler in order to protect the safe operation of the gas boiler, improve operational efficiency boiler, make sure to check the work before the boiler starts, every detail can not be ignored. 1, check the safety accessories, thermal instrumentation, electrical instrument should be intact; 2, check the connections, whether the water leakage and the furnace body line; 3, check the waste line, the water line, return line should be smooth; 4 , should check the line voltage is 380V, the fluctuation should be within ± 5%; 5, oil-fired boiler and a filter pump check whether normal oil, gas boiler check the gas pressure is normal, not too high or too low, the oil supply opening valves; 6, check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Water Supply System opens each valve (including the water pump and water valve before and after the boiler); 7, check level gauge, the water level should be in the normal position, to prevent false water level, if the water can be manually Sheung; 8, check the pressure conduit the valve must be opened, the wind deflector must all flue opening; 9, each knob inspection control cabinet are in their normal position; 10, a check valve should be steam boiler in a closed state, the papermaking hot water boiler dealer circulating pump valves should be closed state; 11, check water softening equipment is operating correctly, create a variety of indicators of soft water meets national standards. Carefully do the above inspection, the basic conditions for the fuel gas boiler safe and economic operation.
Gas steam boiler load changes in the water level of air pressure adjustment What happens next: load fluctuation gas steam boiler water level of the air pressure regulating what impact the boiler load refers to the amount of steam is supplied outside?. When the variation amount of steam needed outside world, boiler pressure, temperature, level crossing will move. When the load increases, the pressure drop in the water level is low, the air supply should be increased and the amount of coal. While enhanced combustion, and gradually increase the amount of water to maintain normal air pressure and water level. When reducing the load, the air pressure is high the water level rises, the amount of coal should be reduced and the air volume, reduce combustion, then the appropriate amount of water to reduce or suspend the water supply, the air pressure and water level in the stable nominal range, then press normally combustion and to adjust the amount of water. When reducing the load, the pressure rise when the water level is low, to increase the amount of water should be, until the water level returns to normal, then the need for air pressure changes and the load situation, and to adjust the combustion water.
Oil-fired boiler and gas boiler as the difference between the early stages of construction to complete our economy, our people's spiritual and cultural efforts to increase investment, with the attendant is demanding on the environment, air pollution is coal-fired boilers of large, first in the state it's now a rigorous, but the attendant is it a substitute for oil-fired boiler and gas boiler, that they have any difference? They belong to energy saving equipment, the combustion products of carbon dioxide and water, will not pollute the environment. The biggest difference is that they use different fuels, gas boilers use natural gas, city gas as the fuel, light oil, heavy oil which is used as fuel. In contrast gas boilers, boiler fuel cost is much higher than gas boilers, therefore, it is common for companies do not have a gas boiler operating conditions or institutions to use. Oil-fired boiler and gas boiler difference between: 1, different fuel: the former light oil, heavy oil as a fuel, which uses natural gas, city gas, liquefied petroleum gas as fuel. 2, the burner different: the former use of oil burners, gas burners later use. 3, different cost: the former high cost, about 1-2 times the cost of the latter. The same point fuel boilers and gas boiler: 1, the same boiler: the same tonnage same steam boiler or papermaking hot water boiler dealer of the boiler body. 2, the same auxiliary components: in addition to the burner, auxiliary oil-fired boiler and gas boiler accessories equivalent tonnage same. 3, the same production process: The process of production and processing were carried out in accordance with the same process and production standards. These are the difference between the oil-fired boiler and gas boiler, want to help you choose.
