Abstract

The utility model relates to a waste wood energy source combustion furnace. A furnace body (9) is composed of an outer barrel (13) and an inner barrel (14). A heating water tank is arranged between the outer barrel (13) and the inner barrel (14). A smoke and flame pipe (15) is arranged in the heating water tank. The interior of the inner barrel (14) is lined with an ash blocking wall (27) and an ash blocking wall (28). The ash blocking wall (27) and the ash blocking wall (28) separate the inner barrel (14) into a first combustion chamber (29), a second combustion chamber (30) and a third combustion chamber (31). The waste wood enters the first combustion chamber (29) from a material inlet pipe (19), and the waste wood is ignited and combusted. The insufficient-combusted waste wood in the first combustion chamber (29) orderly enters the second combustion chamber (30) and the third combustion chamber (31) to be sufficiently combusted. The heat efficiency is high, the waste gas has no black smoke and harmful gas, and the utility model saves the combustion of minerals of a great amount of coals, etc.

Description

Waste log energy combustion furnace

The utility model relates to a kind of combustion furnace, and especially a kind of is the horizontal combustion furnace of fuel with wood machining residues (being wood shavings, sawdust, leftover pieces etc.).

The purpose of this utility model provides a kind of waste log energy combustion furnace, makes fuel with waste log, fully burns, and does not produce black smoke gas and harmful poison gas, and is free from environmental pollution, can save a large amount of mineral combustion material such as coal.

The purpose of this utility model is achieved in that and adopts the high-quality boiler steel to make shaft, shaft is made up of inner core and urceolus, the axial line of inner core is 100～200mm place under the axial line of urceolus, top at urceolus is provided with outlet pipe, temperature tube, bleeder pipe, safety valve connecting pipe, inspection opening, the bonnet boom hoisting, be provided with gauge manifold at its side, water inlet pipe, the blast pipe that is provided with blow-off pipe in the bottom and communicates with inner core, the front end face of shaft is provided with the flue door, fire door, feed pipe, shoot door, the rear end is set to openable bonnet, also be provided with cleaning door on the bonnet, inner core is connected inner core with the inner core supporting in the bottom with urceolus with urceolus.In inner core, in the front end block furnace wall is arranged, block has ash retaining wall in the middle part, this ash retaining wall is not built the top, top is unimpeded, and building in the rear portion has another road ash retaining wall, and this ash retaining wall bottom is unimpeded, top is built and is stubbornly refused to lead to, and inner core is inner because of being separated into first combustion chamber, second combustion chamber, the 3rd combustion chamber cutting apart of two ash retaining walls from front to back.Bottom in first combustion chamber is provided with fire grate, feed pipe and shoot door respectively at the top of fire grate and below, first half is built refractory brick in fire grate with the upper edge inner core in first combustion chamber.At the pyrotechnics pipe that some is set in first major part between inner core and the urceolus, pyrotechnics pipe two is led to the 3rd combustion chamber and pipe respectively, and the space between the inner/outer tube is and adds hot water.Feed pipe on the combustion furnace front end face can be hinged with feeding screw, can safe ready ground be sent in the stove hall by timber.

Since adopted technique scheme, the waste that can solve waste log, waste log can burn therein fully, does not produce harmful exhaust, has protected environment, and owing to its sufficient combustion, thermal efficiency height can be saved a large amount of fossil fuel such as coal simultaneously.

The utility model is described in further detail below in conjunction with drawings and Examples:
