auxiliary heating system boilers

When the auxiliary heating system boilers model selection, the number of users of the construction area, the average height of each frame, the radiator, if geothermal (if geothermal, double press area hours calculated, which may be selected from a large area thirds two).

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.

Residential area points run low nitrogen auxiliary heating system boilers What? For now use low nitrogen boiler is very wide, many industrial applications and even district people's lives is also used to this type of boiler, because it has been so special transformation is relatively energy-efficient and less likely to pollute the environment So widespread has been recognized and loved people. However, in order to further ensure safety, when the boiler is running low nitrogen residential area should be to comply with the following points. A, water temperature and to control the speed at the time of low nitrogen Sheung residential district boiler start of operation of the boiler and the temperature of each component is uniform and ambient temperature, as the temperature inside the combustion boiler starts rising, since the boiler relatively thick wall so that the outside temperature rises more slowly, resulting in a temperature difference generated inside and outside wall. Nitrogen and low boiler manufacturers find the temperature difference between the inside and outside will be greater as the thickness, so if the water temperature rises too much, it is possible to make the internal boiler is deformed to form cracks. Nitrogen is low boiler manufacturers emphasize To avoid this situation, one should control the Sheung speed and the water temperature, so as to be uniform so that the temperature rise in the inner and outer walls of the boiler, in order to protect the boiler is not destroyed. Second, to control the rate of temperature increase of the combustion process in which a low nitrogen boiler startup, with the temperature inside the pressure will rise together, so that both are simultaneously carried out, so control the rest of the wanted speed it is necessary to control the rate of temperature rise. And during the gradual lifting of the drum it will not only be a thick outer wall of a temperature difference occurs but also other parts of this will change so that thermal stress is generated, which for low nitrogen adverse boiler maintenance, is low nitrogen alert boiler manufacturers must control the thermal stress and reduce as much as possible to avoid excessive heating adversely affect important parts of the pressure line, flow orifice and the like. Third, the boosting speed should be adjusted during the low nitrogen pressure inside the boiler rises, the need to go through several different stages, and the pressure is increased by a certain entity, the increase rate is not the same saturation temperature of the working fluid, and the lower the pressure, the corresponding saturation temperature rise rate greater height and unit pressure as the pressure increased, increase in the saturation temperature of the water will become increasingly smaller. Thus professional boiler manufacturers of low-nitrogen of a boost very slow in the beginning, but at relatively high pressure until the situation can be improved appropriately boosted by adjusting the speed of impotence, because the pressure rise and temperature rise have mutual influence, it is not possible to separate transfers, must be considered to operate.

Seven, auxiliary heating system boilers size Weight

In the construction of the boiler room, according to the weight and size of the design of electric steam boilers, you must allow sufficient space for boiler use.
