the energy-efficient gas boiler steam machine

Horizontal steam the energy-efficient boiler steam machine with a boiler boiler you know take you through a horizontal steam boiler Generally speaking, we use boilers have very many models, according to their different fuels of different works, there are different, the boiler itself institutions, divided into many, the Take the steam boiler, there are still sub-ordinary boilers and steam boilers of it, for this horizontal steam boiler, his characteristics is not the same. Boiler fire resistant concrete arch from ramming. After the arch low and long, and therefore good combustion, flue wings and side wall refractory material sintered brick. Boiler front wall, back wall using a common bricks. Grate air distribution reasonable, the combustion chamber is large, strong coal applicability. Adapt to all types of bituminous coal or anthracite, mixed coal. Full combustion. Since the high temperature flue gas enters the first settling chamber, and then into the wings on both sides of the stack, before the smoke box, smoke and dust so good effect. Water circulation simple, reasonable structure and components under pressure, in the case to ensure water quality, completely safe operation. Combustion equipment for the quick grate, combustion apparatus installed in the manufacturing plant, transported to the site can be directly mounted on a foundation. With a reasonable structure, compact, low consumption of steel, the boiler performance, weight, frame size and capacity of the domestic product has obvious advantages compared. It is a horizontal type boiler quick fire tube boiler, refrigerant natural circulation. The boiler drum from the heat exchange system, the left and right header, composed of the water wall, the main furnace wall with a heating surface, convection tube inner drum portion and the drum.

A heated the energy-efficient boiler steam machine is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .

Maintenance of the the energy-efficient boiler steam machine plant food during the maintenance shutdown has deactivated which is to prevent boiler corrosion. Since boiler shutdown, a large boiler humidity, poor ventilation, if long-term in a wet state, oxygen in the air with the metal heating surface of the wet complete contact, the inner surface layer of brown rust generated; in addition, often the heat receiving surface of the gas side accumulating ash particles during operation, after the shutdown in the humid environment, will cause corrosion of metals. In the boiler shutdown process, the main reason is the presence of moisture and corrosion of metal surfaces of the air. Thus, as long as the metal surface or a metal surface with dry air (oxygen) isolation, can effectively prevent corrosion. The length of the parking time, there are packing, Paul dry, wet security, ventilation PROTECTION. 1, pressure maintenance Pressure maintenance is suitable for up to one week shutdown of the boiler. The residue pot pressure 0.05 ~ 0.1MPa, temperature slightly above 100 ℃. Boiler pressure and temperature to maintain regular methods using steam heating the water adjacent to the boiler, a heating boiler or intermittently. 2. Dry Dry care maintenance is a method to protect the desiccant into the pot and in the furnace. Its purpose is to keep no water jug. The utility model is suitable for long-term or seasonal shutdown boiler heating boiler. Open manholes and hand holes, the header and the drum-dried. When wet boiler room, with appropriate use of the furnace heat or light burning wood, so that the furnace, the furnace wall flue drying. After drying the boiler is cooled, the opening and tray formulated desiccant tube is placed in the pot, and a collecting box grate, then tightly closes the inlet aperture, and a valve connected to the hand hole to prevent air from entering. For some Mifengbuyan valves, plug board should be increased.

To speed up solving air pollution prevention and control Liaoyang key and difficult issues, Liaoyang city government combined with the actual circumstances of the sky to win the Battle of implementation. Details are as follows.

1, promote clean heating. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. In strict accordance with the "Notice on and of" (Municipal Office Liao Fa [2018] 19) requirements, minutes from the town to the countryside level steady implementation of clean coal-fired heating, natural gas heating in an orderly way, actively promote electric heating, heat pump heating scientific development, expansion of industrial waste heat heating, heating to accelerate improvements in the proportion of clean, implement the relevant provincial price policy, ensure the power supply. 2019 Clean heating rate should reach 44% in 2020 to clean the heating rate should reach 49%.

2, control total coal consumption. According to energy-saving emission reduction Work Leading Group Office of the City "on the issuance of Liaoyang control total coal consumption program of work (2018-2020 years)" (City of Liaoning Office Savings Fa [2018] No. 3), the city's total coal consumption do control. Vigorously for shutting down energy consumption, safety, environmental protection and other 300,000 kilowatts coal-fired units of non-compliance, capacity indicators for shutting down the unit, allowing the transaction or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. In 2020, the city's coal accounts for the proportion of total energy consumption control to 58.6% or less.

3, in-depth implementation of coal-fired boiler control. Increase the small coal-fired boilers (including coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities) elimination efforts. According to the principle of small demolition and Japan to promote clean energy use, developing the approach to co-ordinate the establishment and management of inventory ledger. Strengthen ecological environment, housing and urban construction, industry and information technology, market regulators linkage, strictly control new coal-fired boilers. 2018, 10 steam tons / hour (or 7 MW) coal-fired boilers and focus on the completion of the phase-out of county level and above all the urban area and old inefficient coal-fired boilers small tasks within the industrial park, small demolition boiler mission of 111; 2019, to phase out coal-fired boilers to further improve standards, expand the scope to promote the elimination of urban built-up area of ​​20 steam tons / hour (or 14 MW) and coal-fired boilers, in addition to special planning according to urban heating heating boilers other than essential to retain, urban built-up area 20 steam tons / hour (or 14 MW) coal-fired boilers to be eliminated and all.

4, the development of industrial furnaces governance special action. Development of industrial furnace remediation plan to carry out an intensive investigation, the establishment of various types of industrial furnaces inventory management. Increase the non-compliance of industrial furnaces out of efforts to speed up the elimination of small and medium gas furnace. Encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Key areas banned fired stove, the coal-fired cogeneration substantially eliminated heating pipe network coverage heated oven (furnace); out hearth diameter of 3 meters fuels gas furnace, a fixed bed to increase fertilizer industry intermittent coal gasifier reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke. The industrial furnace governance as key tasks of environmental inspectors, who have not included in the list of industrial furnaces were included in the autumn-winter peak load shifting production program.
