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.

The double horizontal pot water tube advantages of solid fuel boiler is mainly composed of upper and lower horizontal pots, convection tube bundles, water wall tubes, down tubes and headers. The front part of the boiler is a furnace, and a water-cooled wall is arranged around the furnace; the upper and lower horizontal drums are located at the rear of the furnace, and the two drums are connected by a curved water pipe. Most of the combustion equipment uses superheaters, economizers and air preheaters. The high-temperature flue gas flows from the upper part of the furnace to the convection flue through the heater. It first rises upwards and then rises in an S shape, flushes the convection tube bundle laterally, and then folds down into the tail flue, and then passes through the economizer and air. The heat exchanger is exhausted by an induced draft fan and a chimney. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa).

What a question on the advantages of solid fuel boiler must pay attention and timely resolution? For us, the awareness and understanding of the boiler, although already accumulated a lot, but it still has a certain gap compared to the predetermined learning objectives and desired. Therefore, the next major work, is to continue to learn and understand the products of the boiler, so that we can acquire some new knowledge from, thus, make yourself a lot of benefit. 1. boiler, chimney for its antiseptic and what measures can be taken? Chimney corrosion on the boiler, on the specific measures are mainly two, this one is made of stainless steel, to production, the second is the use of a large number of carbon steel plate thickness to be, this is the case, it may be more durable, so to extend its service life. 2. When the boiler severe water shortages, can I pay the operation? This, then, is not. Because, when the boiler severe water shortages, it is urgent to shutdown immediately instead of pay. At this time, the package is not clear soda water level, and, if forced to pay it, due to the huge temperature difference will, therefore, be of great thermal stress, so that damage to the boiler, the worst case, there may explode accident. So, we will come to these conclusions. 3. The pressure boilers should be how to see? Also, what is the high-pressure water pipe? Boiler pressure boiler, which boiler refers to a boiler body opening to the atmosphere. Thus, under any operating conditions, the pressure gauge on this kind of boilers, which are in the zero position of the pointer. High-pressure water supply pipe, which means a high pressure in the boiler, the water is supplied to the electric conduit between the pump outlet and the inlet of the economizer, it is primarily a. FAQ boiler, above these is essential, therefore, to give specific answers, so that we have a thorough understanding of, and a correct understanding, rather than a smattering of knowledge, so, for application of knowledge, is also a disadvantage. Therefore, only seriously, to grasp and use, to make learning a certain meaning and value.

How to determine the purchase of energy-efficient gas advantages of solid fuel boiler is not

Select an energy-efficient gas boiler, as opposed to ordinary gas boiler, saving fuel and input costs are extremely significant. Use energy-efficient gas boiler, to achieve full combustion of fuel, not only improve fuel efficiency, but also improve the overall thermal efficiency of the boiler. In the other parameters the same, the same amount of water is heated to a certain temperature, the higher the amount of fuel used in combustion efficiency of the boiler efficiency is much lower than the low gas boiler.
