Qingzhen gas oil horizontal legislation for industrial boilers for industrial boilers us in the process of selection, will run into many questions. Here, the author with the mass analysis. How many major industrial boilers RMB yuan by the number of boiler industry needs a host, burner and how much the yuan, accessories (circulation pumps, instrumentation, the entire valve) how much the yuan integration. RMB to select the number of factors need industrial boilers, where the main active use: the production is not the same brand, manufacturer, output technology, testing, industrial design, steel and other election. Inside, very very important factor is the following: (i) automatic switch-over fired hot water boiler manufacturer's ability manufacturers the ability to choose will, product quality. Because of, a competent companies, excluding occupy more weight on the market, enjoy adequate experience. Han, as well as the power of the authority of the design of the product. The quality of industrial design standards, product quality pressure is considerable. A direct impact on the reliability of the product to be used next, energy conservation, safety, and convenience standards. Second, the selected parameters grade steel steel is the basic product output. Standard eligibility criteria steel, industrial boilers are sealed to protect the smooth efficiency. Some brands use mainly the small and non-standard steel, will result in industrial boiler products, poor reliability, high energy costs, followed by security retained the scourge of the customer's situation, it was even enough time save costs, but Xi refers to the loss of the palm. ③, when the output level of industrial automation equipment manufacturing output in the boiler, cut, rolled, divided, very very important process. These three processes, compared to the artificial manipulation, the use of automated production equipment, advantage is very obvious. Due to manufacturing automation, there will be increased precision, less mistakes. It is also, large industrial boilers brand products, higher than focus on the root causes of small-scale production of the brand. Because, finally, closer and more connected to industrial design standards, eligibility criteria for obtaining the best instructions output. 4, testing procedures some domestic enterprises, sometimes through no harsh industrial boiler products, factory link test. Pressure is terminated, it is as product standards. This extreme behavior is definitely not fulfill our responsibilities. Standard testing procedures, will bear the main: load verification, validation inert gas, the test weld gap, the sealing of the test, and factory test run. Essential, balanced. Only in this way, protection is available to the customer standard products for customers at the time of the next use, to avoid the occurrence of non-compliant products, customer pressure to normal production and operation. 5, most of the service level maintenance of small brands, maintenance of maintenance is not. Full after-sales support personnel appointed agent responsible. But most of the agency staff, there are very few authoritative art team. After the non-compliance occurs, it occurs stop passing the buck, and the results may not be achieved. To sum up, that is, how much the yuan, the stress factors of industrial boilers need. Basically, there are good, good industrial boiler product how much the yuan, plus a host of industrial boilers burning machine, almost in per ton, 100,000 or so.

Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.

Since Prime Minister Li Keqiang in the "five" proposed "Blue Sky Wars," after the strategic plan states that China provinces and cities are doing to improve environmental protection. Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program," coal-fired units will conduct a comprehensive reform.

"Program" also proposed to complete the transformation of ultra-low emission electricity generation units appropriate to increase the number of hours. Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. Coal-fired generating units to increase the technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal heating boiler pipe network coverage and the range of loose coal. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume. Before the end of 2020, within a 15 km radius of 300,000 kilowatts of heating and cogeneration power plant above range, in the case of cogeneration heating load to meet the heating needs, in addition to the need to retain the peaking boiler, coal-fired heating boilers and small coal-fired thermoelectric behind all closed down integration.

In addition, long-term control of total coal consumption in accordance with planning requirements, Jilin Province, to continue to reduce the amount of coal consumption, coal consumption in new coal projects to implement alternative reduction, by 2020, reduce the proportion of coal accounting for the province's total primary energy consumption to 63% the following. According to focus on the use of coal and clean use of principles, focusing on reduction of non-power coal, increase the proportion of electricity from coal, the state-assigned task is completed, the province's electricity by 2020, the proportion of thermal coal coal consumption reached more than 55%.

In the future, the province will carry out a comprehensive environmental aspects of governance, economic development and environmental protection go hand in hand.
