commercial gas steam boilers

Works chemical plant boilers is what works what chemical plant boiler is? Energy conversion device is a boiler, a boiler input energy comprises a chemical energy, electrical energy, thermal energy of the flue gas temperature and the like. After conversion of the boiler, steam, water or high-temperature organic heat carrier having a certain thermal energy to the boiler outlet. Mainly used in thermal power plants, ships, locomotives, industrial and mining enterprises. The main principle is a use of the chemical energy released by combustion of boiler fuel or industrial waste heat transferred to the water container, the water reaches the desired temperature or pressure of the steam heating apparatus. Boilers and boiler furnace two parts at the same time, water enters the boiler, the boiler heating surface in the steam - water system will absorb heat transferred to the water, so that by the hot water reaches a certain temperature and pressure to produce hot water or steam or, is introduced into the application. cation. In the combustion apparatus part, sustained release heat of fuel combustion, high temperature flue gas produced by combustion heat propagation, to transfer heat to the boiler heating surface, the temperature itself is gradually reduced and finally discharged through a chimney. Works chemical plant boilers is what - Classification commercial steam boilers: First, the fuel can be divided into: 1, coal-fired boilers, 2, oil-fired boiler, 3, gas boiler, 4 electric boiler, boiler and nuclear 5, 6, waste heat boiler, etc., most top four, the most common, the lowest operating costs of coal-fired boilers, but a large area, serious environmental pollution, the requirements of operators, gas boilers high degree of automation, operating costs than coal, accounting small land area, requiring fewer operators, I did not use electric boiler, but running costs should be the highest, but the small boiler footprint, environmental protection is the best, the other boiler is not introduced, because I do not understand you the meaning of. two. The heat transfer mode can be divided into water-tube boilers, the thermocouple tube boiler, water tube boilers and fire tube boiler. Usually gas fuel boiler fire tube boiler, typical Type: series WNS (horizontal combustion boiler combustion chamber), this boiler characteristics: simple structure, the rated capacity of the evaporator is generally small (typically 10 tons or less, have a greater , but generally not more than 35 tonnes), starting the furnace pressure faster, lower quality requirements boiler; coal-fired boilers typically water boiler. Tube boiler, water tube boiler high thermal efficiency, but the complex structure of the boiler a higher quality requirements.

It may be suitably improved electrical commercial steam boilers burner material: the electric steam boiler at the time of adjusting, if the wind speed control of the secondary is too small, it will lead to too close the gas fire, the burner nozzle so that thermally deformed until failure. Further, when the adjustment is not timely gas boiler load changes the level of the upper orifice of the secondary throttle will be cooled so that the burner is not burning. It may be suitably improved electrical burner of a steam boiler materials, steel materials excellent recommended to choose, and adding wear resistant features. Selection of swirler vanes refractory steel material, so to avoid burning due to swirling vanes configured fall burner opening deformation damage.

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.

How how electric commercial steam boilers maintenance electric steam boiler maintenance 1, boiler maintenance, must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, electric steam boilers stop running long time, turn off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, with a slow fire the burner drying pot (burning time not too long, to avoid damage to the boiler), then all of the drained gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve.
