Abstract
The utility model relates to an air heater for recovering waste heat of flue gas, which comprises a plurality of parallel metal plates; wherein, an air channel or a flue gas channel is formed between every two neighboring metal plates; the air channel and the flue gas channel are arranged alternately; the direction of air inlet and the direction of flue gas inlet form an angle of 90 degrees and the directions of the inlet and the outlet of the air are in the same direction; both sides of the air channel are respectively provided with sealed aluminum laths which are parallel with flow directions of the air or the flue gas. The air heater has the advantages of simple structure, large heat transferring area and high recovering efficiency.
Description
Technical field
The utility model relates to a kind of flue gas waste heat recovery steam air heater
Background technology
At present, boiler smoke is directly to be discharged in the atmosphere by air-introduced machine mostly, and this a part of heat can not get reclaiming, and causes the loss of the energy, and directly the discharging back influences the atmospheric environment health.
Summary of the invention
The purpose of this utility model provides a kind of flue gas waste heat recovery steam air heater, and this steam air heater is simple in structure, and heat transfer area is big, the organic efficiency height.
For achieving the above object, the utility model by the following technical solutions:
This flue gas waste heat recovery steam air heater, it comprises: the metallic plate that polylith is parallel, constitute air duct or exhaust gases passes between every adjacent two metallic plates, air duct and exhaust gases passes are alternately arranged, the air intlet direction becomes 90 ° with the direction of gas approach, the Way out of gas and importer are to consistent, and described gas passage both sides are equipped with the sealed aluminum lath that parallels with air or flue gas flow direction.
This steam air heater can make the cigarette temperature descend 20 ℃-30 ℃ through experiment, and the temperature of air can improve 30 ℃-45 ℃, and boiler efficiency improves 1%-1.5%.
The utility model has the advantages that: simple in structure, heat transfer area is big, the organic efficiency height.
