closed vessel oil gas steam water boilers
Why gas steam boiler energy saving may be why gas steam boiler energy saving gas steam boiler design pressure should be slightly higher than the high work pressure, and not less than safety valve opening pressure. Design pressure gas furnace using 1.2 to 1.5 times the working pressure; liquid pressure furnace design should take pressure of 1.05 to 1.2 times; Liquid furnace gas and steam outlet pressure differential should be greater than 0.15MPa (1.5kgf / cm2). Temperature gas steam boiler import and export, from the design of both economic and security point of view, to design gas-steam to run a suitable temperature difference in the system, this temperature difference should be less than 30 ℃. Gas steam boiler is a closed loop, the return oil temperature and oil temperature only a 20-30, 20-30 words, only heating the temperature difference can reach temperature gas steam boiler. The steam boiler is added to cold water, the cold water is heated into steam to heat heating device, steam becomes condensed water discharged 60-70 degrees. Therefore, the role of energy saving functions!
6 ton oil gas condensing boiler used in paper mill
Last year, a paper mill based in Australia contracted a 6 ton oil gas condensing boiler which model is WNS6-1.25-Y.Q. Our company is responsible for all production work of this 6 ton/hr gas condensing steam boiler. The product utilizes condensation technology to effectively reduce the exhaust gas temperature and improve boiler efficiency. Moreover, the boiler adopts a number of advanced technologies to reduce the emission of harmful substances such as SOx, NOx and COx, and is an efficient and environmentally friendly solution for industrial boilers.
Gas-fired steam boiler safe operation Tidbits gas steam boiler safe operation Tips 1. The operator should be familiar with the structure and principles of the furnace and the production of basic requirements for thermal equipment, and constantly sum up experience in practice, control coal thickness, so that the full combustion reduce chimney smoke, protect the equipment in a safe, efficient operation. 2. The new oil furnace or restart long home, gas steam shall dehydration stage heating requirements. 3. export oil temperature should be set below 280 ℃, when the oil temperature exceeds 200 ℃, should pay more attention to temperature, oil temperature should slow down, only non-oil change and over-temperature operation. 4. close contact with production, timely and slow down the oil temperature, while meeting production requirements, taking oil lower, will help extend the life of gas and steam energy savings. The normal oil level: the lower tank oil level is low, high-high oil groove. This ensures that the emergency shutdown when cold oil replacement system and prevents air from entering the pipe. When the high slot in a low oil level should start to replenish gas steam injection pump. 6. The circulation pump is allowed outage in the operation of the burner, when the pump is failure or power outage, Fan stop, depending on oil temperature and take appropriate emergency measures: rapid opening valve 7, the cold head tank oil up through the furnace coils to the low tank. 8. Coal and wet coal hearth fire or discharge out of the furnace, non-water washed pouring furnace. These measures should be completed within 3 to 5 minutes, to prevent the high oil temperature coke deposits other accidents. 9. normal shutdown, the oil temperature should be reduced to below 100 ℃, stop the pump before. 10. When the outlet pressure differential below the set value, the induced draft fan should outage. Then there is a fault system, feedback should be immediately removed or, if necessary, should pressure fire outage. 11. fireman should stick to their posts, do a good job operating records and shift work, and regular inspection and maintenance equipment.
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.
