Select 2t 6t fired steam boiler fuel gas of good or good? Steam boiler has a lot of varieties, the most common classification is based on it can be divided into fuel to burn natural gas and electricity and fuel burn of. When buying a steam boiler, a lot of people do not know that we should buy natural gas or fuel steam boiler steam boiler. Gas boilers and oil boilers are our two most common ways the boiler. If you want to use natural gas steam boiler, the need to ensure that there are local gas can be switched on; if you want to use oil-fired boiler, the procurement needs daily oil tank and oil tank buried, placed in position and good design, so that the fuel supply to the boiler. Gas-fired boiler burning natural gas, it has the primary energy saving, high thermal efficiency strengths, oil-fired boiler burning diesel fuel is light, it has a simple fuel reserves by the fuel supplier strengths affect small. The primary operating costs and fuel gas steam boiler steam boiler related with local energy pricing. Per ton of steam vapor is about to use the side 80, if the offer by gas 3 yuan / square to count, that is, 240 / ton operating costs. Steam per ton of about 66kg of light diesel oil is used, if the press 9 yuan / kg fuel offer calculated, then the cost of steam is about 594 yuan / ton. To compare quotes from the fuel, then, natural gas will be cheaper than oil.

Recently, Wuhan City, introduced in 2019 to embrace the blue sky action plan for speeding up the optimization and upgrading of industrial structure, promote the optimization of energy structure adjustment, implementation of transportation restructuring, deepen industrial pollution control and other tasks proposed solution.
Among them, in terms of optimization and upgrading of industrial structure, we will study and formulate more stringent industry access threshold, no new heavy chemical and paper industry projects within 1 km of the Yangtze River and Hanjiang River shoreline. Strict implementation of ecological protection red line, the bottom line of environmental quality, resource utilization on the line, environmental access a list of constraints.
In optimizing the energy structure, the city's ban on new coal-fired generating units, supporting the construction of new projects is prohibited owned coal-fired power stations, will not be new coal-fired boilers. Increase efforts to promote green buildings, new buildings full implementation of green building standards. In deepening the industrial pollution control, referring to Beijing and Xi'an subsidies, launched a comprehensive transformation of low nitrogen gas boiler. Before the end of 2019, the district completed at least 50% of the area within the low-nitrogen transformation tasks 10 steam tons / hour or more gas-fired boiler.
Factors industrial boiler energy-intensive factors which have high energy consumption of industrial boilers which 1, energy consumption is low management level industrial boiler is too large, there are currently a lot of long-term business. On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.
Boiler fire phenomenon, how to do 1, furnace pressure fluctuations or to limit and alarm. 2, no flame detector flame, flame flameless television display. 3, flue gas oxygen abnormal fluctuations. 4, steam pressure steam temperature dropped drastically. 5, furnace black, black smoke chimney. 6, the flue gas temperature is reduced. 7, MFT action, turbine trip, splitting the unit. Cause 1, the furnace combustion conditions organizations unreasonable, improper wind coal proportion. 2, the load is too low, unstable combustion conditions without oil combustion vote, or vote, although oil but not good combustion results. 3, cast oil, poor quality oil, oil spray gun is bad, low oil pressure, oil system failure. 4, poor coal quality, coal is too rough, the water is too large pulverized coal combustion adjustment is not timely. 5, the primary air temperature, air pressure is too low. 6, boiler MFT protection action. 7, a large area of the furnace coke collapse, smashing off the flame. 8, severe water wall pipe explosion will blow out the flame. 9, all coal-fired condition, mill pulverizing system failure caused most or all trips. 10, a part of auxiliary machinery such as a fan, blower, fan, air preheater tripped, causing unstable furnace combustion conditions. 11, sootblowing properly, resulting in a large number of normal operation of the furnace ash effects of fire inspection of the boiler. 12, bottom seal damage. Treatment 1, the boiler fire, MFT should be action, otherwise manual MFT. 2, normal inspection device linkage linkage MFT, confirm that all fuel cut. 3. quickly identify the cause, try to eliminate the boiler can be re-ignition, the recovery unit operation. 4, when the mill started again after the trip, the trip must be the primary air tube mill full purge. 5, the MFT operation, checks, Fan normal operation, automatic furnace vent. 6, the MFT movement, check all the secondary purge air damper position is set, the total air volume is automatically adjusted to 30 ~ 40% BMCR sufficiently purged air volume. 7, the MFT operation, when the turbine is in a state disk drive, the disk drive must continue until the normal turbine eccentricity, before re turn red. 8, if temporarily unable to identify or eliminate the cause, restart and could threaten personal safety equipment, non-start. 9, processing according to the corresponding predetermined remaining MFT.Free Chat
