When the weather gets colder and colder, people will choose different ways of heating, one of which is more convenient is the fuel-fired boiler, but many people do not understand his use, so take a look at the following. Classification: fuel-fired boiler is a kind of boiler which uses diesel oil, waste oil and so on. Its overall structure and arrangement are similar to coal-fired boilers, and the common classification is mechanical and steam materialized. Features: the bottom of the oil-fired boiler is mostly made of the heat preservation bottom tilted to the back wall, which is the bottom of the heat preservation furnace, in order to obtain good combustion characteristics. This kind of boiler, for those who do not have a natural gas pipeline, also hope The oil-fired boiler is a good choice when the cost of normal operation of the boiler is low. The fuel-fired boiler is an important symbol of the progress of the times, in order to serve the human being well and further perfect according to the needs of the people.
Because of the particularity of the oil-gas 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.
Leshan City, Sichuan Province issued a notice "Leshan City to win the Battle of the blue sky plan", the program made specific control measures and methods for the quality of atmospheric environment, as follows.
1, and strictly control the total coal consumption. Timely expansion of high-pollution fuel combustion zone ban scoping, year by year break down total coal consumption reduction targets. In 2020, the city's total coal consumption is not more than 7.075 million tons, accounting for primary energy consumption fell to below 30%. Strict control of new construction, renovation, expansion of coal projects, new coal project implementation year coal consumption reductions times the amount instead. Wutongqiao, multiple Qianwei existing administrative areas with coal-fired boilers, in accordance with the total capacity and operation of the boiler coal consumption reduction principle of substitution, central heating facilities in the new base construction of the park, but it must be stable ultralow emission standards, and to eliminate the heavy pollution weather and atmospheric environmental quality standards as a prerequisite for a stable schedule, bear autumn and winter peak load shifting and eliminate future responsibility.
2, to carry out comprehensive improvement of the boiler. Increased inspection efforts to prevent the resurgence of small coal-fired boilers. The city is not implemented before the air quality compliance and stability, a ban on new or expanded coal-fired boilers. Municipal Economic and Information Technology Bureau, the Municipal Ecological Environment Agency jointly entrust qualified units, the implementation of the transformation of ultra-low emissions, the use of coal industry enterprises to carry out at least once a major air pollutant emissions supervisory monitoring every year. Ban on new fuel boilers and other cogeneration coal, fuel oil. New gas-fired boiler construction simultaneously low NOx combustion facilities, low NOx combustion is completed before the end of December 2019, the transformation of existing gas boiler. City and county built-up areas the implementation of ultra-low emission biomass boilers transformation.
3, bulk coal use to carry out special rectification. Using coal for use in all high-quality coal, coal mines by 2020, all built to retain supporting washing facilities, the city's raw coal rate of 90%. In accordance with the principle of progressive advance of Pingba first, and then the mountains, the "coal to electricity," which, according to local conditions in key areas to promote rural villages, "coal to electricity, coal to natural gas" work. A total ban on the circulation and use of low quality coal, bulk coal investigate unlicensed business activities according to the law, high-pollution fuel combustion zone ban is abolished bulk coal sales outlets, to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves . In 2020, within 30 km surrounding county town and township range of the main city of almost no bulk coal use.
4, accelerate clean energy alternatives. The implementation of "gasification of the city, alternative energy, clean alternative" projects, subsidies to change the electric boiler. 2020 non-fossil fuels in primary energy consumption should increase to more than 38%. Research to develop new energy truck traffic right of way, to encourage policies on sustainable management, new and replacement buses, rental, sanitation, postal services, commuter, logistics and other light vehicles with electric vehicles. By 2020, postal services, urban delivery, light sanitation basic vehicle for the electric car, for the van passes light logistics vehicle essentially electric cars, buses central city using all new energy vehicles and reached the country six emission standards for natural gas clean energy vehicles.
Construction of gas 1th steam boiler steam requirements for the construction of a gas boiler requirements, gas steam boiler installation for the construction of the boiler room have certain requirements, must comply with national requirements in the construction process. Gas and steam 1, the construction of a gas steam boiler room requirements 1) boiler room must comply with the "boiler energy saving technical supervision and management regulations" and "industrial boiler room design specifications" requirement. Gas steam 2) boiler room should have sufficient light and good ventilation, have the necessary antifreeze measures. And boiler room should stay away from schools, housing and densely populated areas. 3) the position should be close to the boiler room heating equipment, in order to reduce head losses and heat loss from the hot oil piping circulating pump. 2, furnace heat carrier device is arranged in claim 1) the sump should be lower than the lowest position of the heat carrier furnace and heat system 1 m, in order to put the net organic heat boilers and systems, sump and furnace heat carrier spacing less than 5 m or separated by a partition wall. It should be fitted with a sump exhaust pipe, which exhaust pipe diameter should be large and specifications than the inflation tube. 2) position of the expansion tank should be higher than the other devices and the piping system, the system must be higher than the maximum bottom level 1.5 m. It should not be installed directly above any one boiler, organic heat carrier to prevent overflow cause a fire. 3) the sump vent pipe, expansion tank, should be connected to the outdoor safety. Can not be mounted on the vent pipe to the valve, to ensure that the tank, the expansion tank to atmosphere to ensure atmospheric pressure operation. 4) the high volume of the expansion tank should be greater than 1.3 times and all the organic heat carrier furnace heat the entire heating systems is at the operating temperature is increased due to thermal expansion of volume. 5) low volume tank furnace heat carrier to be less than 1.2 times the total amount of organic heat. 6) hot oil circulation pump should be at least four weeks for 0.5 m space, and the inspection to ensure the installation routine, the need for maintenance.Free Chat
