Burner and flue installation and electrical installation and the fuel supply system of the burner 1, burner 1) before installation read "burner manual", according to the installation requirements. 2) Burner mounting flange, the middle requirements, to ensure the burner to the 400kw fired boilers flue gas does not leak at the interface. 2, the installation of fuel supply system (see schematic) Note: To prevent a fire caused by generation of static electricity in the fuel tank, the tank should have a good grounding. 1) supply system tank top tank top-feed system suction recommended distance between the back plane and the tubing inside diameter of the oil pump axis, the total length of the suction pipe Hm, m, no greater than DL6-34DL40-75DL100-250Di = 10mmDi = 14mmDi = 16mm0.51.03030401.535452.03535452.540503.0404050 Notes: (1) when there is an elbow or valve on the suction pipe, each of the length of the suction pipe to be minus 0.25m. (2) Di recommended internal diameter suction pipe and return pipe. 2) the distance between the bottom of the tank bottom of the tank supply system supply system pipe inner diameter recommended oil pump axis and a plane, the total length of the suction pipe Hm, m, no greater than DL6-34DL40-75DL100-250Di = 10mmDi = 14mmDi = 16mm1.03030401.535452.03535452.540503.04040504.045 Notes: (1) when there is an elbow or valve on the suction pipe, each of the length of the suction pipe to be minus 0.25m. (2) Di recommended internal diameter suction pipe and return pipe. 3, gas pipe installation requirements Burner gas line itself has been connected, the intake port, the intake pipe bends should be minimized and good sealing performance requirements, to prevent leakage. (Iv) a chimney installation, to prevent leakage, the leakage of smoke, to prevent smoke inhalation chamber. 2, a vertical mounting, a right angle bend bends should be avoided. 3, the top of the chimney must be water-resistant measures. (E) mounting a power switch with electrical connection box 1, the power switch should be considered easy to operate, away from heat, fixation, meet the design requirements. 2, the use of 220V (380V), 50HZ power source, and a ground line. 3, voltage instability in the region use, should be safe regulators. Or affect the normal operation of the combustion engine. 4, the power cord to the electrical box must be connected in strict accordance with the requirements, otherwise, there will be dangerous!
Reform technology of coal-fired 400kw fired boilers combustion mode retrofit of coal-fired boiler by means of this technology, proper pulverized coal can be injected into the proper position of furnace chamber, and appropriate suspended combustion can be added on the basis of furnace row layer combustion, which can achieve a certain energy saving rate. For fuel oil and gas-fired boilers, the old and backward burners can be replaced by new energy-saving burners.
Since 2019, Taiyuan continue to adhere to the principle of priority to improve air quality, in order to significantly reduce heavy pollution weather as the main direction, ongoing action to combat air pollution, management depth to promote coal-fired 400kw fired boilers to achieve 35 tons of steam coal-fired boilers "clear zero".
In accordance with the gas will change, given the need for, after the first stand broken, do not break the principle of non-stand, Taiyuan will continue to carry out the transformation of rural areas, clean heating, heating is expected to complete the transformation of 30,000 before the end of October, the city's rural areas clean heating coverage rate reached 70%.
To reduce coal pollution, coal-fired boiler will also promote the in-depth treatment. October 1, seven more than 65 tons of steam coal-fired boilers and ultra-low emissions completed the transformation. Seven out of 35 tons of steam coal-fired boilers to achieve 35 tons of steam coal-fired boilers all clear.
In the region of the pollution control aspect, the binding improved air quality requirements, the complete electricity instead of coal, coal gas for generation of clean alternative energy area, included in "ban on coal zone", the implementation of joint sheet control. Meanwhile, to further increase the intensity of investigation ban within the "ban on coal zone" small coal-fired facilities, enhance the level of protection clean heating, ensure clean heating effect, and resolutely put an end to bulk coal burning complex, consolidate the "ban on coal zone" construction achievements.
In terms of market control, prohibit the use of more than 1% sulfur, ash than 16% of the civilian bulk coal. Before the end of the civil bulk coal sampling of coal sales business monthly coverage rate of 10%, annual sampling coverage of 100%. Investigated sales of low quality coal units and individuals in accordance with law, concentrate on cleaning up, straighten, banning non-compliance bulk coal supply channels, to crack down on the use of low-quality coal sales behavior, non-coal washery slime, the coal into the civilian market.
How to improve the thermal efficiency of gas steam 400kw fired boilers steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased tail gas steam boiler heating surface of, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.Free Chat
