Since March this year, Haidong Qinghai province to implement the central issue environmental supervision feedback coal-fired boiler rectification work, speed up the production of green, zero emissions work processes, and improve air quality, to develop a series of coal-fired boilers on the rectification requirements of the program, as the initiative, strike out, to carry out rectification work in coal-fired boilers within the city, complete elimination of high energy consumption and serious environmental pollution of coal-fired boilers. Planned before the end of 2020, out of the new regulation since 2013 registered 10 tons of steam per hour and a total of 35 sets of coal-fired boilers. To date, 24 have been dismantled coal-fired boilers, the completion of 69% of the total demolition tasks.
In campaigns, the Haidong Market Authority established the Secretary for the head of the leading group, and achieve the "four guarantees" work. First, strengthen organizational leadership, promptly convene a special meeting arrangements, set up to director, head of the leading group, strict rectification requirements, compaction responsibility, division of labor, supervision and implementation, to ensure that the tasks, responsibilities, personnel, time to implement place; second is to strengthen the publicity and guidance, held a coordination will promote, publicize national environmental policy so that the people in charge to enhance environmental awareness, consciousness of serving the overall situation, to ensure that the main responsibility to put in place; the third is Duocuobingju full supervision of the remediation coal-fired boilers demolition work to ensure full demolition tasks to complete the rectification of high-quality, on-site in time for the use of special equipment write-off procedures to monitor and update the information platform, the rectification work will not stay dead; fourth is to strengthen the rectification pin number system and standardize accounting, according to " Qinghai province to implement the central requirements of environmental protection inspectors feedback pin number rectification work approach ", the timely development of ledger collect relevant information, to ensure that the sales numbers for the record rectification work tasks.
Up to now, the central feedback requirements Haidong included the removal of 35 planned coal-fired boilers have been demolished 24 units, of which the county mutual aid, Ledu District, safe area, Minhe County, Hualong County coal-fired boiler demolition has been completed work to complete the renovation work ahead of coal-fired boilers. Next, Haidong will continue to increase coal-fired boilers eliminated, remediation publicity work to do mass persuasion to explain, guide active community participation, active support and cooperation to carry out "ban on burning 'governance activities. Actively persuade pressure coal-fired boiler units to implement the "coal to oil", "coal to gas", phasing out coal-fired boilers high pollution, high energy consumption, encourage economic boiler unit to switch to environmentally friendly, safe and efficient biomass, natural gas, etc. clean energy.
Importance of continuous Feedwater equipment in Gas-fired Steam BoilerThere are two kinds of feed water methods for steam boiler, steam feed water and electric feed water. Steam water supply equipment mainly refers to water injector and steam reciprocating pump, usually acting as backup water supply equipment in boiler. Another commonly used electric feed-water method is through the electric centrifugal pump and vortex pump to feed the water. During the operation of steam boiler, the feed water equipment is usually required to have the active control function. The water level can be lowered to a certain azimuth to actively open the pump to feed the boiler, and the inlet water to a certain direction can also actively stop the pump. Hot water boilers can also be recycled according to in / out water temperature or heating conditions. So gas boilers are usually equipped Use an electric centrifugal pump or vortex pump instead of steam-powered feed-water equipment. The feed-water equipment in gas-fired steam boiler is a very important equipment in all boiler systems. It is responsible for supplying raw materials to steam boilers; allowing it to produce the steam it needs to be used. In the process of boiler operation, it is necessary for the water supply equipment to run synchronously so as to supply water to the boiler continuously, so that the boiler can get enough water supply to run normally and safely.
Comparison of natural gas and coal-fired boiler boiler: natural gas, including natural gas boiler water boiler, gas hot water boiler, gas steam boiler, which is also called natural gas hot water boiler natural gas heating boilers and gas boilers bath, days as the name suggests refers to the gas-fired boiler fuel for the boiler of natural gas, natural gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for natural gas as a steam boiler, heating, boiler equipment for bathing. Gas boiler comprising KS-Q water natural gas boiler, CLHS (CWNS) natural gas hot water boiler, LHS (WNS) natural gas and steam boiler, wherein the natural gas comprises a natural gas hot water boiler heating boilers and gas boilers bath, with the realization of the country "West-East" project, natural gas boiler gradually become the people's choice. "Special Equipment Safety Supervision Regulations" as defined in the boiler is the use of various fuels, electricity or other energy sources, the costumes, the liquid is heated to a certain parameter, and external heat output devices. Which is defined in a range equal to or greater than the volume of the pressure of the steam boiler 30L; outlet pressure is greater than or equal to 0.1MPa (gauge pressure), greater than or equal to the rated power and the pressure of the hot water boiler 0.1Mw;
Depending on the operating characteristics of small mobile electric steam boilers, mainly to properly regulate the drum and induced draft fan. The chamber negative pressure is guaranteed ± (5-10) premise mm water column (water column ≈9.8Pa 1mm) to minimize the amount of the wind, to extend the residence time of the flue gas temperature in the furnace, reduce exhaust gas temperature.
