December 29, 2018, Yulin City, Shaanxi Provincial People's Government issued an iron fist rule on blue haze win the Battle of three-year action plan (2018-2020 years) (hereinafter referred to as the "Program").
That "plan", mainly to adhere to all the people cohabitation, source control, continued implementation of air pollution control operations, improve the city's air quality, determined to win the battle of the blue sky efforts. Details are as follows.
1, the construction of high-pollution fuel combustion zone ban. Deadlines have been designated high-pollution fuel combustion zone ban construction of combustion zone ban prohibits the sale, burning polluting fuels, a ban on new or expanded high-polluting fuel burning facilities have been built in the city and county governments should provide the within switching to natural gas, liquefied petroleum gas, electricity or other clean energy sources.
2, to further promote the bulk coal governance. Promoting rural residents, agricultural production, clean energy alternative to coal-fired commercial activities, take electricity instead of coal, substitution of gas for coal, and biomass, wind and solar and other clean energy alternatives.
3, accelerate the transformation of governance-fired power plants. Accelerate the construction of wind power, photovoltaic and other non-fossil energy electricity generation. Implementation of the provincial special program, shutting down vigorously eliminate environmental protection, energy consumption, security is not up to 300,000 kilowatts coal-fired units. Capacity to shut down the unit, coal consumption and pollutant emission targets to carry out a transaction or replacement.
4, prohibiting new coal-fired central heating station. New heating all use natural gas, electricity, heating Renewable energy (including biomass clean heating, solar heating, heating and other industrial waste heat), to give priority to distributed clean energy central heating, residential buildings do not have the conditions, you can access municipal centralized heating.
5, to carry out comprehensive improvement of coal-fired boilers. The city is no longer a new 35 tons of steam per hour of coal-fired boilers, 65 tons of steam per hour and above all coal-fired boilers and energy-efficient ultra-low emissions to complete the transformation. Increase the small coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment and other efforts to phase out coal-fired facilities, phasing out 10 tons of steam per hour and coal-fired boilers. Low NOx combustion gas boiler to carry out the transformation. Before the end of 2020, the conditions of the conventional gas combustion boiler completed low nitrogen transformation, after transformation of nitrogen oxide emissions is not higher than 80 mg / m. Urban built-up area of ultra-low emission biomass boilers implement reform.
6, strengthen straw Jinshao main responsibility. To carry out special inspections straw Jinshao in the summer harvest and autumn harvest stage. Due to open burning of straw to prevent regional heavy pollution caused by the weather.
7, pin good job of storing system for gas production. Gas supply priority for city residents and substitute coal for heating in winter. "Coal to gas" adhere to the "gas will change" to ensure safe construction, safe use, and safety management. Orderly development of natural gas peaking power plants and other interruptible customers.
8, speed up the upgrading of rural power grids. Urban counties to formulate a work program. Power grid enterprises to co-ordinate the construction of power transmission and transformation project to meet heating demand for electricity residents. Encouraged to promote regenerative and other electric heating. Governments at all levels to "coal to electricity" project supporting grid should be given support, coordination "of coal to electricity," "coal to gas" land for construction.
9, improve energy efficiency. Continue to implement the action of the total energy consumption dual control and strength. Improve energy efficiency standards, develop, promote energy efficient technologies and products to achieve key energy industries, energy-saving equipment standard full coverage. New projects in key areas of high energy consumption per unit of product (output) energy consumption should reach the international advanced level.
10, to accelerate the development of clean energy and new energy. Optimization of wind energy, solar energy development layout. Where the conditions of availability of resources, to encourage the development of county biomass cogeneration, biomass briquette boilers and biogas.
Gas hot water difrence wet back boiler and dry back boiler controller function analysis of gas hot water boiler product introduction gas hot water boiler can satisfy the heating and hot water supply. If the heat exchanger in the pipeline hoisting decency, the boilers to meet a predetermined bath and warmed simultaneously. Gas hot water boiler with obvious environmental protection, energy-saving properties, Security Council, and other intelligence operations, very convenient. In addition, since the operation of rationality and incentives the government of the New Deal, gas hot water boiler Everybody increasingly been pro-gaze. Gas hot water boiler controller function of resolution. 1, Encyclopedia Chinese Patent liquid crystal display, embedded luminous incandescent lamp, noon, night, regardless of the display contents at a glance 2, animation image as significant level, the heating, the valve case, an alarm situation, well known boiler 3, cpuU automation 中央处理器 all intensive program on a number of sub-integrated ic, ease of use, high intelligence level, use simple variable, fully functional. 4, with the time setting, temperature setting, setting valve for setting, automatic setting, etc. actuated to set the pressure, set free working efficiency. 5. With low water level alarm (anti-aircraft firing), high temperature alarm, Gao pressure alarm, a chain support capabilities (shutdown) and other alarm action to remove security risks. 6. detailed self-diagnosis, record and store alert messages, free to check the alarm condition is conducive to regular inspection and maintenance.
However, different manufacturers for different positioning of the difrence wet back boiler and dry back boiler, to meet customer groups should not be, we can not make a specific ranking. But we still can from the usefulness of products, brief characteristics of high-quality boiler manufacturers, as well as the characteristics of the product.
Internal boiler fouling does not occur, it increases the life of the boiler, is generally 1.5 to 2 times the life of the boiler. Heat exchanger portion with stainless steel, corrosion-resistant, the design service life of 20 years.
Most efficient modern boilers supplied are wetback type. Dry Back Boiler. The reversal chamber in dry back boilers is not completely surrounded by water. The posterior part is exposed to the atmosphere. This leads to the increased radiation losses, as the radiant heat is lost to the atmosphere instead of going to the water as in wet back boilers.Online chat
