electric heating steam boiler for sale
By the end of 2018, Wu'an Municipal People's Government of Hebei Province issued a notice on the issuance of "blue sky Wu'an winning three-year action plan to defend the war", referring to the notification: By the end of 2019, the city has a depth of discharge conditions for reconstruction the coal-fired units completed in-depth treatment, meet the relevant standards. Implementation of coal-fired power management depth. Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, security is not up to 300,000 ten million coal-fired units.
First, the implementation of in-depth treatment of coal-fired power plant
Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. 2018, 2019, 2020, respectively, by province and Handan given task given the amount of closed down. Heating demand complete transformation of 600,000 kilowatts grade pure condensing units, high-capacity, high-parameter units accounting for 90%
Special action to carry out deeper cuts power industry, coal-fired units in the original ultra-low emissions, based on the further optimization of operational management, improve pollution control facilities, improving removal efficiency, the implementation of colored smoke plume power plant management. Before the end of 2019, the city has deeper emission coal-fired units to complete the transformation of the conditions of the depth of management, meet the relevant standards.
Second, to carry out special treatment industrial furnaces
The development of industrial furnaces comprehensive remediation plan to carry out an intensive investigation of industrial furnaces, establish classification list management. Stringent emission standards, increase efforts to eliminate non-compliance of industrial furnaces, accelerate the elimination of small and medium gas furnace. Under the premise of resources to implement and encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace); out hearth diameter of 3 m or less gas furnace fuels, natural gas use conditions have temporarily , building a unified center of clean coal gas principle; prohibition blended with high-sulfur petroleum coke.
Classification of Oil-fired BoilerCompared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas-fired boilers, such as gas-fired boilers, are the most expensive to operate, gas-fired boilers need to be opened with gas pipelines, then, if there is no natural gas pipeline, and hope that the operation cost of the boiler is low, only the choice of fuel-fired boilers. Fuel-fired boilers are heated by burners, and fuel-fired atomization effects Good fuel combustion, smokestack can not see black smoke, so fuel-fired boiler green, efficient and energy-saving. Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil.
Electric steam boiler is electrically heated by electrical power installed for the manner of thermal energy, so that the completion of the reaction the boiler, the steam output device outwardly, is a new innovation of "coal to electricity" policy.
Work and family considerations boiler shutdown boiler inspection carried out maintenance before restarting operation, the need for a series of maintenance work, combined with the user experience and learning references, be aware of the following specific boiler maintenance work and family considerations. 1. Preparation (1) before the boiler before the boiler equipment maintenance inspection, as in normal shutdown program is stopped, slow cooling, water circulation and ventilation through the furnace, and gradually lowering the temperature of the boiler furnace. When the temperature dropped below 80 ℃, the door opening open various checks on the boiler. Prevent steam, hot water or cigarette burns when opening the door opening. (2) Steam test boiler feed water, should be separated from the sewer line with the respective other operation of the boiler. Blind for a separator plate should be sufficiently strong to avoid high pressure medium in the broken drum is operated. This clearly indicated the blocking position. Combustion chamber and the flue (3) Check the boiler should be separated from other operation of the boiler. Flue and ventilation doors must be closed tight after separating. 2, preparation of the pressure vessel (1) before the container inspection prior to examination, to be completely cut off the connection tube between the container and the gas pressure or other equipment, particularly equipment using flammable or toxic media. Not only must the valve is closed, and must be sealed with blind plates, so that the valve leaks, resulting in leakage of flammable or toxic gases into the vessel, fire, explosion or poisoning. (2) all media in the container to be discharged. Containers containing flammable, toxic or suffocating medium should be cleaned, replaced or sterilized, by sampling and analysis. A power supply associated with the container, such as a container with a stirrer, reversing mechanism, etc., must be cut off, and a clear flag indicating not allowed to connect. 3, a boiler maintenance considerations are (1) Note ventilation and monitored prior to entering the drum, the container, the drum must be opened, all in the hole hand hole in the container and the collection tank, the air convection period and adequate ventilation. When entering the drum and the container inspection, one must monitor the external device. Before entering the combustion chamber or flue must also be ventilated. (2) Note that the detection of electrical safety in wet flue drum and when the lighting voltage should not exceed 24 volts, with electric lighting. In dry flue, using appropriate security measures, it may be no more than 36 volts lighting voltage. When entering the test vessel, should be used no more than a low-pressure proof lamp voltage 12V or 24V. When the supply voltage detection equipment and maintenance tools than 36V, good insulation must be reliable grounding cord. Boilers and containers should not be used flame. (3) removably connecting member pressing the forbidden band in the inspection of boilers and pressure vessels, pressure if the fastener member needs to unload or screwing, must fully release the pressure, before it can be. Bolts or other fasteners can not be tightened or unloaded at the boiler pressure, in order to prevent accidents. (4) prohibits self-test instead of the hydraulic pressure to the boiler pressure vessel test pressure test generally use water as the pressure medium, there is no gas as a pressure medium, otherwise it is very dangerous. For structural reasons the like, water can not be used as a pressure medium test individual containers, when instead of hydraulic pressure in accordance with design requirements, should be thoroughly checked before the test, check the strength and reliability of the measures taken. Prior to implementation should conscientiously implement the design in accordance with the provisions of, and prior consent of the security sector.
