Gas fuel gas boiler for comparing the air concentration, at the burning of the limits, if the flow rate of the combustible gas in the burner is lower than the burning velocity of the fuel occurs in the direction of the flame over the combustion, not only that, but also with the furnace temperature will rise between gas-fired boiler, the flame propagation speed will also speed up, so it is easier to produce tempered, tempering phenomenon occurs once, rescue team burner gas boiler damage, but also serious explosion occurred.
When the boiler is severely short of water, the method can not take rapid cooling, water supply to the furnace is prohibited to continue, otherwise there will be risk of explosion occurred.
The quality of natural gas boilers also have a strong relationship with the device operating parameters and presets. If the operator of the gas-fired equipment to adjust each parameter does not match with the environment, or confusing sequence of operations may also lead to natural gas boilers in the course of the system Caton, excessive condensation water, low pressure or no change in temperature abnormal situation. Therefore, the relevant personnel to operate natural gas boiler must be in accordance with the instruction proper operation boiler, preferably with professional instructors and auxiliary operations. Third, the repair and maintenance of gas boilers
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.

How Does A Boiler Work? A steam boiler operates through a combustion reaction between fuel and air, which ignites a flame into tubes that are submerged in water. The heat from this combustion is then transferred from the tube to the water in which the tubes are submerged. The water is then evaporated into steam.Get A Quote

You find steam boilers in power plants, factories, steam locomotives, etc. The basic idea is simple - water is turned to steam with a source of heat. Fire tube boilers are common. You have a big tank of water with tubes running through it. A burner creates heat (say with natural gas or oil as the fuel), and the hot gases flow through the tubes.Get A Quote
