single drum tobacco powder steam boiler

While its heating system can be used for long-distance transportation pump, heating large radius, however, the heat transfer coefficient and lower thermal efficiency. Low cost which adapt to a wide range of high temperature steam, heat transfer area of ​​the apparatus can be reduced, reducing the cost, but since the steam condensate recovery heat medium difficulty, can cause vaporization of some of the water avid waste. At the same time, even if there is condensate recovery, because the recycling process, and other magazines oxygen doping should the water, it will cause harm to the boiler.

Fuel gas single drum tobacco powder steam boiler cleaning methods and maintenance Comments? Necessity boiler steam boiler fuel gas washing operation over a long period, the inevitable emergence of scale, the problem of corrosion, boiler scale formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation in an oven within a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale. Maintenance 1 gas fuel steam boiler, gas steam boiler feed water must go through qualifying process, which is to extend the life of the boiler, ensure the safe operation of the important issues. 2, feed water temperature should be as close to the furnace temperature, preferably above 20 ℃. 3, the low water cutoff for periodic inspection and maintenance and cleaning apparatus. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. 4, requires periodic operation of sewage per day (per shift) at least once, you should check whether the sewage drain valve due to possible contamination and leaks; if it must be excluded. 5, when the steam pressure is not maintained while the shutdown, the steam boiler space air entrapment generates negative pressure, and therefore should rise again to the fire burning total steam valve is opened. 6, after the smoke tube fouling will lead to increased exhaust gas temperature, so that boiler efficiency is lowered, so that the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling.

Which operating costs Food Factory Food Factory single drum tobacco powder steam boiler steam boiler operating costs have what? Food factory, is the need to consider the cost of running the boiler, after all, spending in this area is great. Therefore, companies need to be accounted for costs in this regard. Because the boiler fuel costs can account for the total cost of running the boiler nearly 90%, other electricity boiler operation is put into the boiler (boiler and burner give (up) pump) lighting and electrical consumption, run-time power consumption), water consumption (water) boiler, labor costs (salaries), boiler maintenance costs. If food plants using natural gas-type gas boilers, steam boilers according to the required operating time per day every day the amount of steam and hot water boilers, above all converted to full-load operation time. Tonnage boiler unit with a gas (80 cubic meters per hour per ton of the boiler) and natural gas can be monovalent. 1 ton gas steam boiler, for example: (1) When the rated evaporation capacity of 1 ton / hour, fuel consumption is 70 cubic meters of natural gas, according to 3.5 yuan / cubic meter natural gas prices (around the price is not very different), natural gas cost of 70 to 3.5 million yuan to 245 yuan; (2) gas-fired boiler during normal use, power is 0.65 times, at full power, so the power capacity of the boiler (1.5kw + 2.2 kW 2 kW) * 0.65 = 3.7 kilowatt, if electricity is 1 yuan / kWh, the power boiler per hour 3.7kw * 1 = 3.7 yuan.

For atmospheric environmental quality issues, Harbin City, Heilongjiang Province, submitted a gratifying annual summary to the people within the city. By 2018, the number of days Hashi ambient air quality standard of 310 days, an increase of 40 days, since the implementation of our 2013 new environmental quality standards, the best of the year.

January 2019, the development of ambient air quality continues to improve. "Good weather" gratifying is the result of Harbin in straw Jinshao, such as firecrackers ban on burning the same time force. Among them, strongly promote the elimination of coal-fired boilers is a top priority. According to statistics, in 2018, out of a total of 1191 Harbin coal-fired boilers to provide strong support to reduce emissions of air pollutants.

Harbin coal-fired boiler was closed down following a major way, into the central heating (including wholesale) or clean heating pipe network replacement. According to the principle "and the appropriate and, should the electric power, the gas should be gas", the clean coal central heating pipe network coverage area, the boiler unit according to claim ownership, the priority region incorporated central heating pipe network; in concentration not covered by district heating network, in accordance with the wishes of the boiler unit property, taking clean renewable energy or alternative heating means, out of coal-fired boilers.

At the same time, various related businesses also improved stations, actively cooperate with the phase-out of coal-fired boilers.

2018 Hashi out of coal-fired boilers intensity of the strongest of the year, out of range built-up area expanded from 9 to zone outside built-up areas, out of a total of 1191 units. In District 9 built-up areas, on the basis of 10 tons of steam per hour out of coal-fired boilers to achieve "clear" on the further elimination of more than 10 tons of steam per hour to 99 coal-fired boilers; county (city) district built out of steam per hour 10 116 tons of coal-fired boiler units; elimination of financial support and utilities per hour 10 tons of steam coal-fired boilers 966 units in urban and outside built-up areas in the 9th district. "Achievements accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants." Director of Air and Noise Pollution Control at the Harbin environment bureau, Li Bin Tang said.

"In order to further solve the pollution problems of coal-fired, 2019, Harbin plans in urban areas, the county (city) built-up area basically eliminated 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, coal grain storage and drying equipment coal-fired facilities; urban built-up area basically eliminated 20 tons of steam coal-fired boilers, push 35 tons of steam coal-fired heating boilers out of the urban built-up area can not be a stable discharge standards; outside built-up areas out of 10 tons of steam can not be stable discharge standards of the following coal-fired boilers. "Li Bin Tang said.
