Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.

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.
According to our learned Wenzhou Municipal People's Government on February 12 issued a notice "Wenzhou Blue Sky win the Battle of action to implement the program (draft)", the details are as follows.
Accelerate the implementation of the relevant arrangements for the deployment of national, provincial and develop natural gas and other clean energy. According to Yi gas of the gas, the electric power should be the principle, and actively guide enterprises to implement energy clean energy alternative, 2020, the basic completion of provincial trunk pipeline construction, the basic realization of natural gas every county, to further improve the urban and rural distribution pipe network construction , the city's natural gas consumption reached 570 million cubic meters, the proportion of non-fossil fuels in total energy consumption to reach the provincial requirements. Orderly development of hydropower, safe and efficient development of nuclear power, optimizing wind energy, solar energy development layout, local conditions to develop biomass energy, geothermal energy and so on. Where the conditions of availability of resources, to encourage the development of county biomass cogeneration, biomass briquette boilers and biogas. Orderly development of natural gas peaking power plants and other interruptible user, in principle, to new natural gas cogeneration and gas chemical projects. Continue to implement the priority generation and purchase of electricity system to ensure the city's renewable energy generation full protection of the acquisition.
Strict new coal project access, the implementation of the reduction of coal instead. According to the State to win the Battle of the sky three-year action plan calls for no new 35 steam tons / hour high-polluting fuel boilers. By 2020, the city's coal accounts for the proportion of total energy consumption fell to 42.8% or less, the city's total coal consumption decreased by 5% compared with 2015. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal in 2020, the city's electricity and central heating coal proportion of total coal consumption reached provincial requirements. Continue to promote alternative energy coal and oil, replace reached the provincial requirements.
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. Strict control of new coal-fired units installed capacity in the region rely on new clean energy generation and transmission to meet outside the main electricity consumption. In the premise of protecting the power system security and stable operation of 2020, to accept the outgoing power levels to at least 38%.
Consolidate construction achievements combustion zone ban, increase efforts to eliminate small coal-fired boilers. According to the National to win the Battle of the sky three-year action plan calls for phasing out the 10 steam tons / hour and coal-fired boilers, the county level and above urban area basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment, etc. facilities; basically eliminated the city's 10 steam tons / hour and 35 steam tons / hour of coal-fired boilers; 35 steam tons / hour and more polluting fuels and energy-efficient boilers to complete the transformation of ultra-low emissions; low nitrogen gas boiler basically completed the transformation; city built-up area of biomass boilers implement ultra-low emissions transformation.
