Abstract

The utility model discloses a high-efficiency energy-saving gas boilerfor living, belonging to the technical filed of coal burning boiler. The prior boiler for living has the shortcomings of low thermal efficiency, high coal consumption and non-conforming smoke blackness standard to the environment protection requirement. The technical proposal of the utility model is that the boiler hearth is internally and respectively provided with a pre-heating area and a burning area, and is also respectively provided with three-time air feeding, thereby making the burning more scientific and rational. The utility model is suitable to be used in heating boiler and drinking boiler.

Description

Energy-efficient coal gas boiler for domestic

One, technical field:

The utility model relates to coal-fired heating boiler technical field, a kind of specifically energy-efficient coal gas boiler for domestic.

Two, background technology:

There is the shortcoming that the thermal efficiency is low, coal consumption is high, blackness of exhaustion is big mostly in existing boiler for domestic, and boiler applying unit not only Coal-fired capacity is big, but also because of blackness of exhaustion is big, and suffer the punishment of environmental administration repeatly.

Three, technical scheme:

The purpose of this utility model is to want to provide a kind of energy-efficient coal gas boiler for domestic, and is promptly capable of reducing energy consumption, can reach the environmental requirement index again.

The technical solution of the utility model is as follows:

This stove is vertical single layer fixed fire grate structure, adopts the gravity-flow ventilation hand to burn.Its primary structure is characterized as, and the tubulation lower end is connected with the water leg divider wall in the stove, and divider wall is divided into precombustion chamber and combustion chamber with burner hearth, and precombustion chamber and combustion chamber are communicated with in the divider wall lower end.Divider wall upper end have be communicated with combustion chamber and precombustion chamber the combustible gas overfolw hole several, and on the furnace wall of divider wall upper end combustible gas overfolw hole opposite position several air inlets are arranged.In the fire grate bottom shoot door being arranged, also is an air inlet, and secondary air mouth and a clean-out door are arranged on the furnace wall, fire grate top.Coal filling hole is positioned on the furnace wall of precombustion chamber upper end.

The theory of combustion of this stove is after coal is dosed precombustion chamber, through destructive distillation, to make it to produce coal gas, the coal gas major part is ploughed under in the combustion chamber from the divider wall lower end, another part enters the combustion chamber from the combustible gas overfolw hole of divider wall upper end, because the air abundance, so burning is fully.

The utility model is provided with air-supply structure three times owing to adopted the coal gas destructive distillation to separate with the combustion zone, makes combustion process more scientific and reasonable, and energy consumption can be saved about 30%-50%, flue dust blackness＜1 grade.

Four, description of drawings:

Fig. 1 is the structure assembling schematic diagram of the utility model embodiment 1.

Fig. 2 is the outer existing structural representation of the utility model embodiment 1.

Fig. 3 is the structure assembling schematic diagram of the utility model embodiment 2.

Five, the specific embodiment:

Embodiment 1: from Fig. 1 and Fig. 2 as can be known, this stove is vertical single layer fixed fire grate, tubulation 10 lower ends are connected with a water leg divider wall 7 in the stove, divider wall 7 is divided into two parts with burner hearth, divider wall 7 one sides are precombustion chamber 2, opposite side is combustion chamber 6, and precombustion chamber 2 and combustion chamber 6 are communicated with in divider wall 7 lower ends, divider wall 7 upper ends have be communicated with combustion chamber 6 and precombustion chamber 2 combustible gas overfolw hole 9 several.In the fire grate bottom shoot door 4 is arranged, also can be described as air inlet one time, a secondary air mouth 3 and a clean-out door 5 are arranged on the furnace wall on fire grate top.With the furnace wall of divider wall 7 upper end combustible gas overfolw hole 9 opposite positions on several air inlets 8 are arranged, coal filling hole 1 is positioned on the furnace wall, precombustion chamber 2 upper end.Other label is 11 water level interfaces among the figure, 12 chimney interfaces, 13 hangers, 14 nameplates, 15 water inlets.

Embodiment 2: as can be seen from Figure 3, the difference of present embodiment and embodiment 1 is that it is to be two precombustion chambers 2 between 6, two divider walls in combustion chamber and the furnace wall that interior tubulation 10 lower ends are connected with between 7 two water leg divider walls 7 of two water leg divider walls.Precombustion chamber 2 and combustion chamber 6 are communicated with in divider wall 7 lower ends, divider wall 7 upper ends have be communicated with combustion chamber 6 and precombustion chamber 2 combustible gas overfolw hole 9 several, with the furnace wall of divider wall 7 upper end combustible gas overfolw hole 9 opposite positions on have also air inlet of a shoot door 4 arranged under several air inlet 8 fire grates, there are two

secondary air mouths

3 and 5, two coal filling holes 1 of a clean-out door to lay respectively on the furnace wall, two precombustion chamber 2 upper ends on the furnace wall, fire grate top.

Claims

1, a kind of energy-efficient coal gas boiler for domestic, comprise vertical body of heater, single layer fixed fire grate, tubulation etc., it is characterized by the interior tubulation lower end of stove and be connected with the water leg divider wall, divider wall is divided into precombustion chamber and combustion chamber with burner hearth, precombustion chamber and combustion chamber are communicated with in the divider wall lower end, the divider wall upper end has several to be communicated with the combustible gas overfolw hole of combustion chamber and precombustion chamber, with on the furnace wall of divider wall upper end combustible gas overfolw hole opposite position several air inlets are arranged, it also is an air inlet that a shoot door is arranged in the fire grate bottom, secondary air mouth and a clean-out door are arranged on the furnace wall, fire grate top, and coal filling hole is positioned at furnace wall, precombustion chamber upper end.

2, a kind of energy-efficient coal gas boiler for domestic as claimed in claim 1 is characterized by, and the water leg divider wall that the tubulation lower end connects in the stove can be one, and precombustion chamber and combustion chamber are in the divider wall both sides; Divider wall also can be two, and precombustion chamber is between divider wall and furnace wall, and the combustion chamber is between two divider walls.
