Diesel Boiler For Industry

Diesel Boiler For Industry

Fuel volume adjustment simple mechanical atomization nozzle adjustment range is usually only 10% to 20%. When the diesel boiler for industry load changes little, the oil pressure in front of the boiler can be adjusted by changing the oil pressure before the furnace, and the purpose of increasing the oil pressure can be achieved by increasing the oil pressure. When the boiler load changes greatly, the atomization plate with different aperture can be replaced to increase and decrease the fuel injection. When the boiler load changes greatly, neither of the two adjustment methods can adapt to the requirements, so it is necessary to change the fuel injection quantity by increasing and reducing the number of fuel nozzles. The adjustable range of the atomizing nozzle of the return oil machine is relatively large. When the boiler load changes, the return valve opening can be adjusted accordingly to change the return oil quantity. Return oil The larger the quantity, the smaller the injection quantity; on the other hand, the fuel injection quantity increases. In normal operation, the fuel quantity shall not be increased or reduced sharply, so as not to cause the sharp change of combustion, and cause the pressure element to expand and shrink abruptly and damage.

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 [2018] 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. New energy-intensive projects per unit of product (output) energy consumption should reach the international advanced level. Local conditions to improve building energy efficiency standards, and increase efforts to promote green building, city guide implementation of green building standards for new buildings. Renovation of existing residential buildings to promote energy conservation, encourage rural energy-saving housing.

How to treat diesel boiler for industry waste water

During the long-term operation of boiler, the water treatment equipment will inevitably aging. When the equipment is in abnormal operation, the pollution density of the water supply is larger, and there is a certain amount of sediment in the water supply process. When the water with sediment component evaporates in the boiler and more sediment materials are precipitated, the boiler pipe will be blocked, the heat dissipation effect will be poor, and the probability of tube burst will occur. The formation of boiler slag will clog the furnace tube and cause tube explosion if it is not discharged out of the furnace at regular intervals. At the same time, it also reduces the heat transfer effect.

Pressure diesel boiler for industry full of water phenomenon causes and treatment of pressure boiler full of water, when the boiler water level above the water table level security scale line, called boiler full of water full of water phenomenon is what causes it? How they deal with it? As follows: 1, when the boiler is full of water, in the water table often can not see the water level, but dark in the table, which is an important difference between full and water deficit. When filled with water, the high water level alarm alert operation; superheated steam temperature decreases; normal feedwater flow is not greater than the steam flow; severe, the water enters the boiler superheater and steam pipes, resulting in water hammer and superheater fouling. So the main hazard is full of water, reduce steam quality, damage that destroyed superheater. 2, filled with water common reasons: (1) operator negligence, strict monitoring of the water level or misuse: Run who leaves his post, abandoned the monitoring of water levels and other instruments; (2) failure caused by false water table level while not recognizing the operating personnel; (3) water level alarm and automatically adjust the water supply malfunction but not to detect the like. 3, found after pressure boiler filled with water: You should rinse water table, water table to check whether the fault, confirm filled with water, close the valve immediately to stop the Sheung Shui to the boiler. Enable economizer recirculation line, reduced combustion, open the drain valve and the superheater, the steam trap pipe until the water level returns to normal, close the drain valve and trap. Identify and eliminate the cause of the accident, adjust the water supply, to resume normal operation. If water hammer occurs when filled with water, the water level in the recovery, should also check the steam pipes, accessories, such as stents. These are the causes of atmospheric phenomena and boiler full of water treatment, boiler full of water or lack of water pressure in the boiler is running a common phenomenon, it requires fireman personnel taken to avoid such accidents.
