What structure and principles of industrial boilers in particular? What structure and principles of industrial boilers in particular? Industrial boilers has become the hottest on the market boiler boiler. Whether it is gas or gas hot horizontal manual feeding fuel water boiler steam boilers, gas boilers generally use natural gas, liquefied petroleum gas and city gas as a fuel gas fuel. First, the working principle of gas steam boiler: the furnace and the combustion heat of the fuel gas steam boiler, heating pot of water evaporated into steam. Water pan (drum) in the furnace gases are fuel combustion energy released continuously heated, increasing the temperature and pressure steam is generated. When the boiling point of water increases with increased pressure, is sealed pot, the pot water vapor expansion is limited, and therefore the thermodynamic pressure (strictly speaking, water steam boiler). It is widely used as an energy source in the drum, the water is heated and vaporized again to saturation. Second, gas steam boiler basic structure: gas steam boilers and boiler drum consists of two body parts protection, instrumentation equipment, automatic control and protection system of continuous safe operation of its composition. This boiler water wall boiler drum boiler drum in the zoning arrangement, the first two return pipe fireworks smog chamber back to the drum. Connected between the drum and the tank, with water-cooling pipe and the downcomer, which constitute the framework of the combustion chamber. The pot is provided at the top with a steam water separator, to reduce the amount of water extracted from the steam. The bottom of the pan heating surface of the drum, and fireworks waterwall tubes.
Electric boiler winter maintenance methods: cold winter approaching, north and south part of the city has gradually begun heating engineering. Boilers for its environmentally friendly, clean, no pollution, no noise, automatic and other effects electricity won the user favorite. So, how to maintain electric boiler should work to ensure the normal winter heating and other purposes?
Yangzhou City in Jiangsu Province, the municipal government issued a notice of 2019 annual remediation tasks boiler, with the text published a list of boiler regulation, as follows.
3, the nitrogen gas boiler oxide (NOx) emission limit is not higher than 50 mg / m transformation, in accordance with other indicators of "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.
(1) prohibits blended with other fuels such as coal, bags and other supporting efficient dust removal facilities, and effectively discharge standards. Emission standards in accordance with "boiler air emission standards" in coal-fired boilers particularly performed emission limits.
Full implementation of the above steam 2,65 t / h coal-fired boiler transformation ultra-low emission, soot, sulfur dioxide, nitrogen oxides, respectively, 10 mg / m, 35 mg / m, 50 mg / cubic meter.
3, disable all kinds of close small coal-fired facilities (tea boiler and furnace operating coal-fired stove, rural production, aquaculture and other coal-fired facilities), switching to natural gas, electricity, solar and other clean energy. In remote rural areas, could be replaced by forming biomass as a fuel, but must use a professional boiler, supporting efficient dust removal facilities, to ensure that pollutant discharge standards, emissions standards refer to "boiler air pollutant emission standards" in particular coal-fired boiler emission limits carried out.
4, a low nitrogen gas boiler and treatment for the transformation, the installation of low NOx combustion by the low NOx combustion mode, etc., to ensure that the nitrogen oxide emission limit is not higher than 50 mg / m. Other indicators according to "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.
5, forming a comprehensive remediation biomass fuel boilers, biomass fired boiler clean-up does not meet the special requirements of the boiler, not supporting a biomass fired boiler emissions and efficient dust removal facilities of non-compliance. To meet the special requirements of the boiler and supporting efficient dust removal facilities, the establishment of accounting and retain more than one year, emission standards refer to "boiler air pollutant emission standards" emission limits in particular the implementation of coal-fired boilers. More than 10 tons of steam installation of gas-line monitoring instruments, and networking with the environmental protection department. Located in the city built-up area forming ultra-low emission biomass boilers implement reform.
6, bulk coal sales within the city limits are all clear according to the law, the use of bulk coal user implementation of the "coal to electricity" for street vendors and other "coal to gas" campaign, a pin number management. At the same time, prohibiting the establishment of long-term supervision mechanism bulk coal, non-bulk coal inflows.
10 tph WNS condensing gas-fired steam boiler project for food industryA steam boiler is an important piece of equipment in the production line of food industry, playing a decisive role in the production processes of stewing, drying, concentrating and sterilizing. Jiaozuzo Tianhong Food Co., Ltd., founded in 1997, is a new type of modern stock company, specializing in manufacturing instant noodles, has the domestic advanced instant noodle production line. With the increasing awareness of environmental awareness and the the enhancement of the populace's cultivation, the government is attaching more and more attention to the ecological environment and ecological civilization. To safeguard the blue sky, the government has introduced a number of environmental protection policies. Jiaozuzo Tianhong Food Co., Ltd. is actively adjusting its industry structure and accelerating the green transformation to respond to the call of new times. Tianhong Food planned to replace the traditional bituminous coal with natural gas as the boiler fuel. The sales manager recommended ZOZEN WNS series gas-fired boiler for the company. This kind of boiler is equipped with a large-diameter corrugated furnace and international advanced low NOx burner to ensure the complete combustion as well as reducing NOx emission. Furthermore, ZOZEN installed economizer and condenser on the tail of the gas-fired boiler, which will effectively lowered the temperature to 60 degrees and improve the thermal efficiency up to 98%.
