Price 8t Diesel Fired Boiler

Gas hot water price 8t diesel fired boiler safe operation of the precautions which the following are a few precautions and accident prone: a convection tube, water wall tube blasting reasons: l, substandard materials; installation does not meet regulatory requirements. The layered wall, does not reach the level of weld quality requirements, and other remnants of the inner tube. Wall causing local overheating and burn; 2, feed water quality does not meet standards. Resulting in scaling the wall structure, affect the heat transfer. And cause the wall temperature of the superheated blasting; 3, due to wear of fly ash. So that the wall thickness reduction; 4, fire shutdown heated too fast or too fast, so that the uneven thermal expansion of the tubes. Causing weld cracking; 5, the boiler load is too high, resulting in uneven burning and the outer tube squib severe coking and other reasons. Preventive measures squib: l, before the installation of the pipe rigorous re-examination, have welding welding process instructions; welding quality to meet the design requirements. After the pipe installation to test the pipeline through the ball, passing rate of 100%. 2, to strengthen the water quality management, a test class and demineralized water to achieve the water quality standards, regular inspection and regular elimination of scale and sewage; 3, water wall tubes and pipes to regularly check the exhaust convection, found deformed or thinned tube to be replaced, keeping in mind that the quality of maintenance, must comply with regulatory requirements; 4, the boiler can not work overload control (predetermined limit), attention furnace combustion process, the combustion to ensure homogeneous, stable; 5, note that the tube coking conditions. To achieve timely clear focus and pay attention to leakage. Second, the hot water boiler explosion: the explosion is very serious accident. Damage to equipment and buildings and heating systems are serious. And often resulting in casualties. Analysis following aspects: 1, design, manufacturing problems a poorly designed, the uneven distribution of traffic in each circulation circuit. Heat too much deviation, solder angular, square, flat plate structure, the steel does not meet the requirements; good manufacturing and repair process. In particular dismay welding quality cells prone to rupture; 2, boiler overpressure eleven operating pressure exceeds the allowable working pressure. Stress plate (internal pressure) higher than the ultimate strength of the steel sheet caused cracking. The main reason is the failure of a safety valve, pressure gauge malfunction, Station Gauges indicate the error. Operating personnel did not take appropriate measures. Not strong sense of responsibility caused; 3, superheated steel overheating burn broken, or too thick scale is mainly due to the water pan grease or other debris caused by blockage heating surface; 4, severe corrosion due to the corrosion by the inner and outer surfaces of the steel sheet the plate thickness is thinned, the strength of the steel sheet insufficient cause rupture; for the above reasons. Summarize a few precautions: l, for manufacturing defects in the design should take the following measures: First, reasonable design. Second, strict related materials, the preparation of three is correct manufacturing processes and process specification cards (including repair), to establish the necessary regulatory Fourth, Fifth, to improve the quality and sense of responsibility of the operators and managers; 2, to prevent overpressure . To ensure safety valve sensitivity and reliability. Regular automatic drainage time. Identify problems in time, also installed on a standard gauge for comparison. And regularly into the metering department inspection; 3, to prevent overheating. You must configure effective water treatment equipment and the establishment of the necessary rules and regulations. So that the boiler is not less furring furring and no accumulation of grease. To check the fouling situation boiler outage. If the scale. You must be promptly cleaned. Scale in order to avoid accretion; 4, preventing internal corrosion. Hot water boiler for larger capacity. The method uses thermal oxygen or chemical oxygen to resolve. In addition. To check the situation of internal and external corrosion. The extent of corrosion repair method such as pile up or Wabu according to (do this before the law, there must be approved by the technical units of the total work program and report to the local supervision departments boiler). To prevent the boiler explosion, regularly carry out the necessary checks on the boiler, at the same time, the boiler management departments should formulate effective measures, operators and managers must strictly enforce minor accidents occurred after the boiler shutdown for maintenance. Tell us about the repair of hot water boiler. 1, when the shutdown may not stop the pump immediately. To be checked after repairs boiler water temperature must be lower than the pump can be stopped when the 50 ℃, at the same time to turn off the water supply valves and heat supply network backwater valve and release the water pot. 2, before entering the boiler, the water must be emptied of all its boiler, sewage emptying all open. Manholes drum, hand holes headers have opened to air convection over time. To enter the interior work, you must pay attention: when someone is working inside. In certain drum outside a supervised. 3, before entering the combustion chamber or flue work. Ventilation must be taken, anti-virus, fire, explosion and other measures. And the total flue chimney flue or other operation of the boiler is connected to the gates are closed tightly. 4, voltage security lighting to use. If the flue inside the drum and more humid. Lighting voltage can not exceed 12V. If dry, the lighting voltage can not exceed 36V. But also have to do to ensure proper safety measures. Do not use open flame lighting.

Hot water price 8t diesel fired boiler Specifications Model: hot water boiler is one of the important energy equipment production and people's lives can not be separated, it is possible to provide heating, hot water and other purposes. Depending on the fuel, the operating environment can be divided into various types, and each type has a large range of optional capacity.

(3) When the steam pressure of the steam price 8t diesel fired boiler is stabilized, if the safety valve is pre-adjusted to adjust the opening action pressure, the pressure adjustment can be carried out, but the steam pressure should be strictly controlled; firstly, one with a high opening pressure is adjusted. Then adjust the other one with low opening pressure; if multiple steam boilers should be adjusted separately.

"Henan 2018 campaign of air pollution control plan" recently introduced, to guide and encourage medium-sized coal-fired price 8t diesel fired boilers eliminated. In the province's foundation 10 steam tons / hour and the coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, the basic elimination of provincial cities planning area 35 steam tons / hour and coal-fired boilers.

Financial awards complement the way:

1, the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

2, the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;

3, the completion of the coal-fired boiler Chaigai before the end of October 2020 no longer give financial awards complement.

Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.
