Three kinds of ventilation 15 ton boiler manufacturings often used at runtime to be continuously supplied to the boiler the combustion air required, and the resulting flue gas continuously drawn, a process called draft process of the boiler. Once the venting is stopped, the boiler will stop running; usually mechanically ventilated, i.e., by means of a pressure head generated by the fan to overcome smoke flow resistance of the duct. Mechanical ventilation currently used in the following three. A negative pressure ventilation chimney addition to using, the former also mounted chimney draft fan to overcome the resistance of all of the smoke, the air duct. This small capacity of ventilation, smoke wind resistance is not so large boiler system is more applicable. Second, while a balanced draft and induced draft fan blower mounted in the boiler smoke, air system. Port to the suction passage into the furnace from the wind (including through an air preheater, and a fuel combustion device layer) overcome the resistance of the entire duct fan; furnace outlet to the outlet stack (including a negative pressure outlet furnace, boiler slag tube after anti heating surface portions of the device and the dust removal) all by flue draft fan to overcome the resistance. This ventilation can effectively into the air, and the furnace flue boilers and all run under negative pressure, boiler room of the safety and health conditions better. If compared with negative pressure ventilation, boiler air leakage is small. Currently in heating boilers, the most balanced ventilation. Third, the only positive draft blower mounted in the boiler smoke in the air system, with its head against the resistance of all the smoke duct. Then the furnace and flue boiler are all working under pressure, and thus the furnace wall and door units are required tightly sealed to prevent leakage of flames and smoke high temperature hurt. This ventilation improves the strength of the heat of combustion furnace, boiler smaller volume equivalent capacity. By eliminating air leakage boiler furnace, flues, and improve the thermal efficiency of the boiler. Positive pressure ventilation, currently has applications in the oil and gas boilers. Boiler draft ventilation is generally balanced and positive pressure ventilation. These are the three common boiler ventilation method, in the process, to constantly add fuel, while also promptly clean up the burned ashes.
Gas-fired steam 15 ton boiler manufacturing safe operation Tidbits gas steam boiler safe operation Tips 1. The operator should be familiar with the structure and principles of the furnace and the production of basic requirements for thermal equipment, and constantly sum up experience in practice, control coal thickness, so that the full combustion reduce chimney smoke, protect the equipment in a safe, efficient operation. 2. The new oil furnace or restart long home, gas steam shall dehydration stage heating requirements. 3. export oil temperature should be set below 280 ℃, when the oil temperature exceeds 200 ℃, should pay more attention to temperature, oil temperature should slow down, only non-oil change and over-temperature operation. 4. close contact with production, timely and slow down the oil temperature, while meeting production requirements, taking oil lower, will help extend the life of gas and steam energy savings. The normal oil level: the lower tank oil level is low, high-high oil groove. This ensures that the emergency shutdown when cold oil replacement system and prevents air from entering the pipe. When the high slot in a low oil level should start to replenish gas steam injection pump. 6. The circulation pump is allowed outage in the operation of the burner, when the pump is failure or power outage, Fan stop, depending on oil temperature and take appropriate emergency measures: rapid opening valve 7, the cold head tank oil up through the furnace coils to the low tank. 8. Coal and wet coal hearth fire or discharge out of the furnace, non-water washed pouring furnace. These measures should be completed within 3 to 5 minutes, to prevent the high oil temperature coke deposits other accidents. 9. normal shutdown, the oil temperature should be reduced to below 100 ℃, stop the pump before. 10. When the outlet pressure differential below the set value, the induced draft fan should outage. Then there is a fault system, feedback should be immediately removed or, if necessary, should pressure fire outage. 11. fireman should stick to their posts, do a good job operating records and shift work, and regular inspection and maintenance equipment.
The difference between oil-fired 15 ton boiler manufacturing and gas boiler difference between oil-fired boiler fuel oil boiler and gas boiler is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, methane, etc.), depending on the boiler What fuel burning device called a burner, gas burner configuration called boiler gas boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference lies in the use of fuel burners burn anything.
Zhejiang Yiwu issued the "Yiwu winning Blue Sky Battle 2019--2020 action plan." Plan to improve air quality, enhance people's happiness index target put forward concrete measures of implementation, as follows.
1, vigorously develop clean energy. In-depth implementation of the "creation of a national clean energy demonstration Zhejiang Province Action Plan (2018-2020 years)" "Zhejiang three-year action plan for natural gas development (2018-2020 years)" and "Jinhua" Thirteen Five "Renewable Energy Development planning". According to "gas of the gas should be '' should the electric power" principle, energy companies actively guide clean energy alternative embodiment, in 2020, the proportion of the power in the final energy consumption of clean energy consumption accounting for the higher level, the city gas consumption amounted to 150 million cubic meters.
2, control total coal consumption. Strengthen energy consumption and total energy consumption intensity dual control, strict new coal project access, new (modified, expanded) construction project coal consumption reduction of coal instead. By 2020, the city's total coal consumption by 2015, down from more than 5%. Continue to promote alternative energy coal and oil, replace reached the national requirements. No new 35 t steam / hour or less polluting fuels boilers. Strengthening coal quality control, promote clean coal utilization. Before the end of 2020, clean coal utilization rate of 92%, the proportion of electricity than to accept deliveries in 2017 significantly increased.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers, the urban built-up area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically out of 10 steam tons / hour and 35 steam tons / hour coal-fired boilers. 35 t steam / hour and more polluting fuels boilers completed ultra-low emissions and energy transformation. Low nitrogen gas boiler basically completed the transformation. Strict control of the new urban area of biomass boilers. Biomass boilers should be dedicated boiler, blended prohibit other fuels such as coal, and other supporting efficient dust bag embodiment, non-coal, oil, natural gas-fired boilers and the like directly Burning biomass briquettes.
4, the positive development of central heating. Cogeneration units to increase the technological transformation efforts, speed up the heating pipe network construction, improve the heating capacity and the full release before the end of 2020, phasing out the cogeneration district heating pipe network coverage and high pollution coal-fired boilers in the range. In the area where no cogeneration district heating conditions, a plurality of existing small coal-fired boilers, an alternative construction of large-capacity coal-fired boiler in accordance with the principles of the reduction or the equivalent.
5, deepening the construction of high-pollution fuel combustion zone ban. According to "adjust Yiwu prohibit the use of polluting fuels sales area plan" (Yi Zheng Ban Fa  No. 180) documentation requirements, a comprehensive investigation and eliminate high-polluting fuel facilities within the city, to ensure that no dead ends, no blind spots, Finish high pollution fuel combustion zone ban burning building before July 2019.
6, improve energy efficiency. Vigorously develop, promote energy efficient technologies and products to achieve key energy industries, energy-saving equipment standard full coverage.
