Abstract

The utility model relates to a boiler, in particular to a horizontal backfire normal-pressure boiler, which comprises burning chambers, a burnout chamber, an upper feed inlet, an air inlet, a lower feed inlet, a slag removing opening and a chimney and is characterized in that a boiler body is divided into three burning chambers and one burnout chamber through an inclined water-wall baffle plate, an upper vertical water-wall baffle plate and a lower vertical water-wall baffle plate arranged in the boiler body, and a second burning chamber, a third burning chamber and the burnout chamber form a multi-pass structure to enable a flue gas flow to be in an S trend. Compared with the prior art, the utility model has the advantages that: 1. the boiler of the utility model has multiple passes and is in a backfire type, so that fuel is fully burnt, heat energy is released with high efficiency, the environmental protection effect is better, and a superconducting liquid pipe is matched, so that the boiler is more rapid in temperature rise and has high heat efficiency; and 2. a movable grate is arranged in the boiler, so that the boiler is more convenient to operate.

Description

Horizontal backfire normal-pressure boiler

Technical field

The utility model relates to a kind of boiler, particularly a kind of horizontal backfire normal-pressure boiler.

Background technology

At present, the normal-pressure boiler that market produces is a lot, the inadequate problem of ubiquity fuel combustion, and these boilers adopt forward combustions, and programming rate is slow, and the thermal efficiency is low, and fuel can not fully burn, and has not only wasted the energy but also pollutes the environment.

Summary of the invention

The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, energy-conserving and environment-protective, combustion efficiency good horizontal backfire normal-pressure boiler.

For addressing the above problem, the utility model has been adopted following technical scheme and has been realized:

A kind of horizontal backfire normal-pressure boiler, comprise combustion chamber, secondary furnace, last charge door, air inlet, following charge door, breast hole, chimney, it is characterized in that, be provided with inclination water wall dividing plate in the body of heater, go up vertical water wall dividing plate and down vertical water wall dividing plate body of heater is divided into three combustion chambers and a secondary furnace, second combustion chamber, the 3rd combustion chamber, secondary furnace form many return structures to make flue gas stream are the S trend.

Described upward vertical water wall dividing plate reaches down, and vertical water wall dividing plate is provided with many superconducting fluid pipes.

Be provided with moving grate and fixed grate in described second combustion chamber, moving grate and fixed grate are spaced setting, and moving grate connects handle.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model boiler is many backhauls, and reverse combustion type makes the abundant after-flame of fuel, efficiently discharges heat energy, and environment protecting is better, and is furnished with the superconducting fluid pipe, makes boiler heating faster, thermal efficiency height.

2, be provided with moving grate in the boiler, make more convenient to operate.
