A number of factors cause the pressure of the heat efficiency of the boilers market 2019 module are carrying substantially all parts of the coal gas impressive work, use a large extent, avoided the module boiler fouling contamination, while discharging hazardous gas like nitrogen oxides obtained a clamp. Thermal efficiency is an important measure of the rule module boiler, let us study the cause of a number of factors under the pressure of the thermal efficiency of the boiler module. After inquire about the personnel, boiler heat loss module is mainly produced in the bear on these two: the proportion of full combustion air with smoke emission unreasonable heat loss. Reduce smoke emission install heat loss can be recovered in the flue gas waste heat boiler module terminal fitting, or use more advanced features of FGR boiler. The combustion air fully proportional unreasonable non-compliant analysis: General ejector module boiler burner, causing the air-fuel ratio is no way to maneuver to mobilize. Part of the boiler module using a mechanical blower burner, resulting in unreasonable cause fuel ratio factors are the following: the main air-fuel ratio unreasonable encompass divided into two cases: when oxygen is excessive, the excess will be numerous cold is heated, resulting in increased cost of energy boiler module, the thermal efficiency of the boiler module lowered; when oxygen is non-compliance, will produce incomplete combustion occurs module boiler heat efficiency is lowered.
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.
It is reported that Haidong Qinghai positive response to the central problem of coal-fired boilers market 2019s environmental supervision feedback rectification work, to speed up the production of green, zero emissions work processes, and improve air pollution control plan before the end of 2020, out of the central regulation of environmental inspectors feedback 10 tons of steam coal-fired boilers and 35 sets of Haidong since 2013, new registrations per hour.
Haidong county (district) government to fulfill the main responsibility for the area out of small coal-fired boilers, in accordance with their respective administrative areas, to develop the county (district) phase out remediation work plan. A thorough inventory of all the region under pressure coal-fired boiler to install and use cases, and register, identify all cases remediation coal-fired boilers since 2013 new registrations do not meet the requirements, filing one by one. It urged all localities to fully consider the urban built-up area, divided ban on burning areas, local conditions, facilities strategy, apply non-urban area Haidong 20 tons of steam per hour, new coal-fired boilers, and establish normal management mechanism. Meanwhile, arrangements for the rectification of funds, and actively apply for provincial, municipal, county departments of special subsidies, to ensure the implementation of coal to gas coal to electricity, coal-fired boiler, new alternative energy and other projects, and with the central environmental inspectors feedback registration illegal small coal-fired boilers problem rectification work combine to promote the problem has been effectively solved.
2. Environmental policy is required for boilers market 2019 emissions. Coal-fired boilers for waste pollution and energy of the atmosphere is amazing. Many cities have been expressly prohibited by the new economic development zone on the coal-fired boiler, while the use of gas, oil, electric central heating boiler or cogeneration.
3. The boiler is the initial investment, including the boiler unit, ancillary equipment, construction investment and other related costs.Free Chat
