Causes of large Resistance and insufficient Air supply in Oil-fired Hot Water Boiler systemThe hot water boiler system has great resistance and insufficient air supply: the reason is that the fuel particle size is mixed, the pulverized coal occupies the block coal gap, and when entering the grate, it is squeezed and dense by the gate, and the permeability is poor. First, the mass coal cannot be burned through, and there is still a red fire when the slag is discharged. Burn the slag blocking parts, slag carbon content is high; Second, coal leakage is serious; third, large resistance, increased blast, induced fan load, high power consumption. The furnace temperature is low, the coal quality is poor and the combustion condition is not good, the furnace temperature is low, sometimes even extinguishes, a large amount of unburned matter and ash powder blockage the economizer and air preheater, which causes the furnace to be in positive pressure combustion. Arrangement of part of reheater heating surface in hot water boiler In the region of higher smoke temperature, the heating area required by superheater is greatly increased. In order to reduce the flow resistance of the working fluid flow through the heater and increase the rigidity of the pipe, the superheater adopts a larger diameter pipe. In order to increase the ratio of radiation and heat absorption in the superheater system and make the steam temperature characteristics of the superheater steady, the radiant separator superheater and the semi-radiant rear screen superheater are arranged on the top of the boiler furnace. The separator superheater is arranged in the direction of furnace width, each of which is composed of a small screen, which not only increases the radiation heat transfer, but also prevents the rotating smoke flow to reduce the smoke in the width direction of the furnace into the superheater. The effect of temperature deviation.
The competition, the segment is slowly 45 contestants only a female welder, most of the other competitors from China Electric Power Construction, veteran welders in the petroleum, petrochemical, and other large number of country prefix units, with a very rich practical operation of work experience. Faced with numerous welding expert, slowly segment did not flinch and fear, but to actively exercise their welding ability, the old master who humbly ask to try a variety of different welding methods, and repeat the training to do practice makes perfect. By her welded boiler parts forming the United States, no weld defects neat; in her station, welding clean, neatly stacked tools, work order. It is because of her usual work down to earth, hard work and practice, lay a solid foundation for the success obtained.
The double vertical tube water tube boiler can be divided into D shape and KB shape according to its structural characteristics. The D-shaped structural feature is that the furnace is arranged on one side of the double vertical drum and the other side is a convection flue. And the KB-shaped structural feature is that the hearth is arranged in the center of the double vertical drum, because the lower drum is shorter than the upper pot, the empty space is just arranged for the furnace, and the rear is the convection flue.
This user is undoubtedly a bolt from the blue. This means that they lost a lot of direct electricity costs. Insulation measures are so important, why some companies do not give electric boiler installed it?
