Inter-regional Pingdingshan Coal Industry Group Co., Ltd. by the Pingdingshan Shenma Group and two Chinese top 500 enterprises founded by restructuring, cross-industry, cross-ownership and transnational business of large state-owned energy and chemical group, under the People's Government of Henan Province , is the most complete variety of coking coal, thermal coal production base, has Asia's largest chemical production base in nylon. Carefully selected and comparison, fast boiler Pingmei cooperation with party has chosen to provide a 2 tons of steam electric steam boiler (WDR2.0-1.25-II) by a fast side.

The pollution-free environmental benefit of industrial coal fired fire tube hot water boiler is obvious: renewable biomass energy is used as fuel to realize the sustainable utilization of energy. Adopting high temperature subsection combustion technology and low emission of NOX,SO2, dust in flue gas, it is the best substitute for fuel (gas) burner, electric heating and so on. Internal inspection and preparation of hot water boiler, inspection of furnace and flue, inspection of boiler accessories, inspection of automatic control system, inspection of ancillary equipment, inspection of combustion equipment, inspection of auxiliary heating surface, The hot water boiler must do some inspection before running, these checks are not to be underestimated, possibly because of our neglect Cause very serious consequences. Therefore, we must guard against micro, hot water boiler operation before careful inspection of the following items. Including boiler internal inspection and use preparation. The furnace and flue inspection, furnace and flue dust and debris should be cleared. Air duct and flue adjustment doors, gates shall be complete and tight, flexible switches, accurate opening and closing instructions. Boiler accessories inspection, check the safety accessories are intact; cock rotation flexible, easy to use; all kinds of instruments and control devices should be complete, good, clean. After the check has passed, the pressure gauge plug should be kept in working condition. Automatic control system inspection. Inspection of ancillary equipment. The combustion equipment is checked to check if the combustion device is in good condition; the mechanical transmission system, the coal conveying system and the ballast system are tested normally; the pressure degree of the safety spring of the speed regulating box should be appropriate and the lubrication is good; the gauge of the coal brake is correct. Eagle iron neat, intact, ballast board integrity, flexible movement. Check auxiliary heating surface to check whether auxiliary equipment (induced fan, blower, pump, etc.) coupling is firmly connected; triangular belt is properly tightened; lubricating oil should be good and adequate; cooling water is unobstructed. After inspection, install safety shield, test operation separately, and pay attention to the current of idling. Internal inspection and preparation of hot water boiler The inspection of furnace and flue, the inspection of boiler accessories, the inspection of automatic control system, the inspection of ancillary equipment, the inspection of combustion equipment, the inspection of auxiliary heating surface, and the inspection of hot water boilers must be made before running. These examinations are not negligible and may have very serious consequences as a result of our neglect.

Condensing gas boiler with coal-fired boilers What are the differences? Some may have which is not very clear to distinguish condensing gas boiler with coal-fired boilers, here we look at their specific differences, 1. The circulating fluidized bed combustion coal-fired boilers are coal by crushing equipment , by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from the flue gas into the atmosphere, polluting the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions from coal-fired boilers is relatively gas boiler, SO3, NOx is much less. 3. Ventilation general negative pressure combustion coal burning boiler, a combustion process with the base by the induced draft fan and the blower mating fit together to complete coal combustion process, requires a lot of air and the furnace wall due to the leakage of flue excess air ratio of up to between 2.1-2.5. Micro-condensing gas boiler combustion positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion furnace flue wall and running flue outlet air coefficient can be 1.05-1.2.4 fuel combustion safety explosion-fired boilers, furnace explosion hazard unlikely to occur. The condensing gas boilers in the explosive concentration limits encountered fire will explode. More dangerous. The boiler control due to coal fired boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to load difficult boiler operating parameters. And condensing gas boiler is less impact on the factors may be adjusted according to the size of the burner valve load, easy to achieve automatic control.

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.
