Abstract
The invention discloses a boiler flue gas waste heat water tank. The boiler flue gas waste heat water tank is characterized by comprising a shell; an inner cavity of the shell is divided into an upper portion, a middle portion and a lower portion; the upper portion is divided into a gas inlet cavity and a gas outlet cavity; the middle portion is a water tank, and the lower portion is an flue gas channel; the water tank is internally provided with a plurality of heat dissipation ventilation pipelines, and the gas inlet cavity and the gas outlet cavity of the upper portion are communicated with the flue gas channel of the lower portion through the heat dissipation ventilation pipelines; a water inlet is arranged at the upper portion of the water tank, and a water outlet is arranged at the lower portion of the water tank; exhaust openings are arranged at the upper end of the water tank; an ash discharging opening is arranged on the wall of the flue gas channel of the lower portion of the inner cavity of the shell; and the water tank is provided with a liquid level gauge and a thermometer. Normal temperature water in the water tank is heated by means of flue gas waste heat of a boiler; the flue gas waste heat is utilized, fuel is saved as well; meanwhile, steam temperature fluctuations are reduced; and the water tank is simple in structure, low in cost and high in flue gas waste heat utilization rate and good in energy-saving and consumption-reducing effect.
