medium pressure gas fired thermal oil boiler

Boilers which are several general, in what is now the mainstream Why? 1, gas medium pressure fired thermal oil boiler advantages: efficient, clean, environmentally friendly, without manual operation, only need to monitor, small footprint, no transportation fuel, no need to deal with soot, due to the combustion of natural gas free of impurities, without corrosion damage to the boiler and related accessories long boiler life, defined as 15 years, but basically long-term use. Is now mainstream boiler, natural gas is the environmental protection sector, the government vigorously promoted. Cons: You do not know how much that gas prices are calculated according to the calorific value and thermal efficiency, generally bituminous coal per ton of coal (according to 5500 kcal / kg) is approximately equal to 350 to 400 cubic meters of gas. Probably a little slightly more expensive than coal. (No transport, area, ash handling, labor, etc. into the calculation). 2, oil-fired boiler, advantages: substantially the same structure and properties of gas boilers. Disadvantages: higher cost of natural gas is 2 times the boiler, diesel transportation, storage more dangerous, accident-prone. And the domestic diesel supply is unstable, easily interrupted. 3, coal-fired boilers, the advantages: the economy. Disadvantages: 1, requires a lot of ash and coal yard area. 2, a boiler fireman for 4 to 8 people. 3, boiler room and coal yard is very dirty. 4, noise, emissions of dust, nuisance. 5, environmental protection departments often to check an inattentive, he was diagnosed with excessive emissions, maintenance shutdown, fine, very troublesome. 6, coal sulfur content are more severe corrosion of boiler, 10 to 15 years after the basic unusable. Summary: Due to high oil prices and supply unstable now, and now oil-fired boiler has been temporarily withdrawn from the market. Natural gas prices due to regional differences are very different, although you are not sure where the price of natural gas, but natural gas in most parts of the domestic coal is relatively expensive, (only in Sichuan, northwest of cheaper natural gas). Especially large industrial boilers, more fuel, the cost difference is more obvious. Coal-fired boilers to heavy air pollution, with the country on environmental issues more and more attention, more stringent emission requirements for coal-fired boilers, a lot of urban cities, has stopped the examination and approval procedures coal-fired boilers. It is recommended that, if your organization is not large tonnage production of boilers, installation of gas boilers or better, although with a little more than fuel costs, but in the actual operation of the process, you can save a lot of things, while saving area, the environment is clean.

To proceed from reality, should be in accordance with the electric power, gas should the gas, the coal should be coal, should be hot the thermal principle, promote the use of all kinds of clean energy for winter heating cleaning. In order to reduce air pollution and protect people's warm winter as a foothold to enterprises, government promotion, residents can withstand the principle of gas after the first change to gas will change in gas assurance, the price is acceptable on the basis of sound promote the "coal to gas" and central heating engineering, in district heating supply pipe network can not cover, vigorously implement the replacement of coal-fired power heating project.

Good job of marketing system storage capacity for natural gas. Accelerate the construction of natural gas transmission and distribution network, the new natural gas volume priority for life and severe winter areas of urban air pollution and coal for heating alternative. In principle, to new natural gas cogeneration and gas chemical projects.

Accelerate agricultural and pastoral areas "coal to electricity," the process of upgrading the power grid. Coordinate development of power transmission project construction, etc. are encouraged to promote the regenerative electric heating. Around on the "coal to electricity" project supporting grid should be given support, coordination "of coal to electricity," "coal to gas" land for construction.

In accordance with national requirements, shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.

According to air quality improvement requirements to accelerate the delineation of high-pollution fuel combustion zone ban and to expand the scope of, and actively promote the elimination of small coal-fired boilers. The county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers and tea furnace, stove and other operating coal-fired facilities, in principle, to 35 tons of steam per hour, the new coal-fired boilers, in principle, other areas on no new 10 tons of steam per hour of coal-fired boilers. While banned out of coal-fired boilers, pressure boilers market regulators cancellation of registration certificate to use.

The thermal oil heater has wide adaptability of fuels, is suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. It is also equipped with an advanced burner to ensure the NOx emission below 30mg/m3. The waste heat medium pressure fired thermal oil boiler, air pre-heater and economizer are installed on the tails of the thermal oil heaters to effectively improve thermal efficiency, which can reach above 98%.

What is the difference between a gas-fired medium pressure fired thermal oil boiler and a coal-fired boiler?

Both gas and coal can be used as fuel for boilers, but different types of boilers are named according to the types of fuels used, so there are gas boilers and gas boilers. So what is the difference between a coal-fired boiler and a gas-fired boiler, apart from the fuel used in combustion?

1. The fuel used by different coal-fired boilers to exhaust smoke is coal. When coal burns, it will cause serious pollution to the environment by producing larger smoke and dust. However, high-stability gas-fired boilers do not emit black smoke after combustion. Because gas can basically be completely burned, smoke-emitting black poison can reach zero level, the content of SO2 in it is very small, so there is no pollution to the environment.

2, heat loss is different in order for coal-fired boilers to maintain adequate combustion intensity, the use of human or other equipment to constantly add coal to the furnace, when the need for intermittent operation, It takes a long time to raise the temperature in the furnace when starting again, so it will produce great heat loss when pressing fire, and the gas-fired boiler is very convenient to start and stop, and can heat up rapidly during intermittent operation, so as to reduce the heat loss in this process.

3, the different ways of treatment after combustion will produce a large amount of ash after burning in the boiler. In order to maintain the health of the environment, the ash will be transported to the professional slag removal yard for treatment, but gas is used in the gas-fired boiler. There will be no residue after combustion, so there is no need to deal with it. It not only avoids the pollution to the environment, but also reduces the labor intensity of enterprises and the storage and transportation of urban ash.
