Abstract

The utility model discloses a superconductive three-return vertical boiler, it is by outer courage, well courage, the inner bag constitutes, by water piping connection between three courage, the convection bank of flue circumference equipartition and outer courage intercommunication between well courage and outer courage, be equipped with the heat pipe in the well courage, furnace body lower part is equipped with the dome shape combustion chamber of building by laying bricks or stones, the combustion chamber is equipped with the overgrate air, the air lets in the combustion chamber under the grate, flue upper end between inner bag and well courage is equipped with helical fin, the chimney stretches out in inner bag center, the brick ball corresponds chimney below and arranges in on establishing on the smoke and dust discharge hole of well courage bottom conical surface, the experimental result shows, compare with ordinary vertical boiler, this stove can thermal efficiency 15%, economize on coal more than 30%.

Description

Superconduction three backhaul vertical boilers

The utility model relates to a kind of superconduction three backhaul vertical boilers, belongs to dual purpose steam water boiler.

Existing vertical boiler is single backhaul and directly discharges fume, and heating surface is little, exhaust gas temperature height, the contaminated environment that the thermal efficiency is low, coal consumption is big, smoke density is high, serious.

The utility model is at the problems referred to above, and a kind of thermal efficiency, energy-conservation, superconduction three backhaul vertical heaters that soot emissions all can reach national I class district standard are provided.

Task of the present utility model is finished as follows: this stove is made of outer courage, middle courage, inner bag, connect by crossing water pipe between three courages, the convection bank that flue circumference uniform distribution between middle courage and outer courage is communicated with outer courage, be provided with heat pipe in the middle courage, the body of heater lower part is provided with the dome-shaped combustion chamber of building by laying bricks or stones, the combustion chamber is provided with secondary wind, one time wind feeds the combustion chamber under fire grate, flue upper end between inner bag and middle courage is provided with helical fin, chimney stretches out in the inner bag center, and the corresponding chimney of brick ball below places on the soot emissions hole that is located at the courage bottom conical surface.

The utility model adopts three courage heating surfaces, convection bank heating surface, heat pipe heating surface altogether, increased more than three times than existing stove heating surface area, high-temperature flue gas flows to the interior water circulation of courage and forms reverse flow, the heat convection effect is in optimum state, can improve the thermal efficiency 15% than common upright stove, economize on coal more than 30%, the flue between middle courage and inner bag is provided with helical fin, but the conical surface, flue gas rotation centrifugal dust-removing are arranged at the bottom, stir the brick ball, dirt is discharged, and the soot emissions of this stove can reach national I class district standard.

Below in conjunction with accompanying drawing the utility model is described in further detail:
