Exhaust gas temperature factors affect the efficiency of the boiler 1. High boilers (1) ring-shaped heating surface. A protective pot operation due to the heated area ash causing poor heat transfer. Secondly heating surface by erosion wear of the high temperature flue gas, resulting in good convection bank vent for taking soil pipe powder blocking manner with less number F, powder powder increases the number of block f will inevitably result in decreased heat transfer effect of the heating surface, the deterioration of the operating parameters. such that the exhaust gas temperature medium (2) bits leakage furnace, the burner burning roll. Wind refuse mud furnace, burner combustion burning material will travel in incomplete protection technology, resulting in frameshift flame, which led to the degree of BU smoke Mi (3) poor operating conditions. A secondary air must have appropriate warehouse Shan ratio during burning. Secondary air Diao large ring-shaped hold burning effect, will affect the wind. Powder mix. 2. boiler water quality factors is an important indicator of pot care, but also a very appropriate to link, the water quality directly affects the safe and economical operation of boiler protection, internal cleaning of the heating surface of each pier can add endothermic t, It will increase the efficiency of the care of the pot. Shanghai each newly installed boiler heating surfaces are clean, the indicators are good, heat transfer efficiency is higher. But with longer run time, the inside of the tube or bi or furring rights corrosion, resulting in decreased heat transfer efficiency, pot nursing efficiency drops, after scaling or corrosion deterioration. Pot can also cause over-temperature protection wall even Los iron . 3. mechanical incomplete Tanzania Heat loss if the twist burner for burning Yan basin, coal dust mixed into the retaining find not carried out, resulting in insufficient fuel you burn. Shan increase mechanical incomplete burning loss. On the other hand due to air leakage protection Mu. Mi will lead to reduced care. Shan burn rate of decline. Powder fire longer, is not conducive to coal combustion rate, resulting in an incomplete tender burn solid increase in losses. Division personnel to operate the operation level of the level 4. 0 operator is not high, not be reasonably performed with the wind, the rotation speed control discharge protection, timely cleaning, descaling, resulting worthy material is not completely burned proud. Long low thermal efficiency in the actual operation, often occurs due to the experience of the operating personnel, resulting in decreased operating efficiency of the unit, adjust the low level of security decline. 'On the other hand, there is a difference operator P forced cultural quality and the level of practical skills.
In promoting energy conservation work, many of our cities have regulations limiting the city center of coal-fired industrial boilers, requires the removal of small coal-fired boilers, replaced by large-scale coal-fired central heating boiler cogeneration or fuel gas-fired boiler, which because the fuel gas-fired industrial boilers has the following obvious advantages of energy saving. 1) high thermal efficiency of the boiler. Average operating coal-fired industrial boiler thermal efficiency of only 60% to 65%, the lower the efficiency of the boiler capacity is smaller; industrial boiler fuel gas thermal efficiency is generally 80% to 85%, the thermal efficiency of the different capacity of the boiler is not very different, industrial boilers Automatic fuel gas thermal efficiency as high as 93% to 95%. See the combustion efficiency, combustion efficiency of coal-fired industrial boilers average less than 80%, the average industrial boiler fuel gas combustion efficiency of more than 95%, combustion efficiency of most industrial boilers Automatic fuel gas up to 98% to 99% (considering the flue gas condensate after the recovery of latent heat). 2) low energy consumption. Fuel gas combustion boiler generally use a slightly positive pressure, just a fan, no dust, coal, slag removal equipment, running less than half the power consumption of coal-fired boilers; small industrial boilers frequent starts and stops, since the fuel gas-fired boiler stop convenience , that is shutdown completely stopped fuel consumption, unlike coal-fired boiler shutdown device still consumes a certain amount of fuel. 3) Low fuel transportation energy consumption. Noncombustible ash coal and water 30% to 40%, ash after burning and 30% to 40% by weight of coal, half of the group receives only the oil and gas of low calorific value, coupled to the fuel conduit and gas transport, with the transport of fuel oil calorific value of coal and ash transport energy less than energy consumption 1 / 4.4) and steel boiler for producing low energy consumption. Producing fuel gas boiler steel consumption is only 40% to 60% with coal-fired boiler capacity. 5) fewer pollutant emissions. Coal contains a large amount of incombustible components, combustion ash and unburnt coal dust become, the major sources of air; and a coal ash transport, storage, and in particular the field of coal ash open field dust pollution caused by the ground; Dust , slag would cause water pollution. In general, at the same furnace heat release, smoke emission was about 11 times as coal fuel, is about 500 times the gas; of SO2 emissions from coal burning is about 3 times the fuel, gas 4000 times ; about the NOx emissions from coal burning of 3 and 4 times the fuel gas. It is estimated that the greenhouse gas emissions - a coal-fired industrial boilers of the same capacity when the CO2 emission light diesel fuel is about 1.3 times, 1.5 to 1.8 times the combustion of natural gas, city gas twice or more the burning.
Gas chain grate coal fired hot water boiler manufacturers and coal-fired hot water boiler What is the difference? Boiler There are many different types of coal-fired hot water boiler is called coal-fired boilers, which burn gas is called the gas hot water boiler. Well, apart from the name calling is not the same, not the same fuel used in addition to, what difference there is between the gas hot water boiler and coal-fired boilers do? Here versatile efficient and practical to introduce the gas hot water boiler manufacturers. 1, there is the environmental impact of the difference we all know that coal burning when smoke will emerge, these scattered black smoke into the air pollution on the environment which, therefore, coal-fired coal-fired hot water boiler in the use of the process there will be a lot of black smoke, the environment can also cause a very bad influence. However, the gas hot water boiler gas, combustion gas is sufficiently, so use will not have a smoke discharge, wherein gas containing not cause damage to the environment. 2, heat loss generated by coal-fired boilers are different often requires manual or auxiliary equipment will be added continuously to burn coal to the furnace, when the pressure of the fire will cause greater heat loss, if the manufacturer is intermittent when the coal-fired hot water boiler starts up again, the furnace temperature you want to raise to the desired temperature will take a long time. However, the gas hot water boiler can quickly increase the temperature of the furnace, so as to reduce the loss generated when the batch operation. 3, the post-combustion treatment there is a solid body difference coal, coal ash will be generated after combustion, coal ash can not be disposable, it is necessary to transport it to a special slag field. Gas hot water boiler is a gas, the gas is not generated in the combustion of solid waste, and therefore no need to do special processing after the combustion. Thus, coal-fired and gas-fired hot water boiler hot water boiler, although only one word, but a huge difference, and that's obvious, gas hot water boiler has the advantage of more aspects than coal-fired hot water boiler, Therefore, the company could do some good gas hot water boiler which brand, sourcing high quality and reliable gas hot water boiler to use.
After use throughout the winter, the Central Conservatory of Music give us feedback, six V6-99 fully meet the heating needs of the school. And boiler fuel and water requirements are not high, urban water and low-pressure natural gas combustion can operate. The most important point is that nitrogen oxide emissions are very low and very happy to recommend it to others to do the brother of boiler units. --customer feedback
