Multiple protection devices take you through the oil steam fired steam condensing boiler oil steam boiler water level protection, boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. Steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. Safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection, having imported burner flame protection means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.
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. 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.
Because of the particularity of the oil-gas fired steam condensing boiler, from the initial construction preparation to the long-term acceptance of the project, there will be some problems to be paid attention to, and what should be complied with? Boilers need to follow the steps step by step to complete. What needs to be observed in the process? Oil and gas dual-use boiler installation before construction, first in accordance with the rules to first handle the boiler installation approval formalities, pending quality and technical supervision bureau approval after! Safety valve is an indispensable safety protection device in industrial boiler. Lever type safety valve can be often used, it can be divided into two types: single lever and double lever. Well, it was run in an industrial boiler. How does the lever-type safety valve work in the process? Why to carry out the air pressure test on the boiler? The lever type safety valve in industrial boiler is basically composed of valve core, seat and important lever, weight hammer and position limiting device. It acts on the valve core through the heavy torque of lever and weight hammer to flatten the pressure of steam. The main energy consumed in the operation of oil-fired boiler becomes fuel oil, so the quality of fuel oil will be directly related to the whole combustion state of the boiler, so how to choose fuel oil to supply to the oil-fired boiler? Generally divided into light fuel oil and heavy fuel oil two major categories. Fuel-fired boilers burn differentiated fuel oil The composition of the oil supply system will be different because of the different characteristics of the oil.
In the bread making process, a water tube steam fired steam condensing boiler can be used to provide steam. The boiler heats the water to produce steam by burning natural gas, biogas, diesel, heavy oil or other fuels. The steam is then transported to different production workshops such as the baking workshop for bread baking. At this time, the request for steam is high. The ZBG oil and gas water boiler is arranged by the upper and lower drums to realize the separation of steam and water, and has sufficient steam and water space, and the steam produced is of high quality and stable parameters. In addition, the boiler is a water tube boiler, which requires high water quality, and the water supply system processes the water to improve the quality of the water supply.
