Abstract

The utility model discloses a straw gasifying furnace which comprises a furnace body (1), a furnace lid (5), an air inlet pipe (12), a secondary air supplying pipe (11), a furnace grate (8), an ash outlet (13), a hot water interlayer (2), and the like. The straw gasifying furnace is characterized in that the top end of the air inlet pipe in the furnace body is higher than the furnace grate and is provided with an air outlet board (7) with a plurality of air outlets, the internal side wall of the furnace body is fixedly connected with a primary air supplying pipe (4), the upper part of the primary air supplying pipe has a gap from the furnace body, the lower part of the primary air supplying pipe passes through the furnace grate, a secondary air supplying pipe (11) is fixed on the wall of the furnace body, and the inlet position of the secondary air supplying pipe (11) is under the furnace grate. The utility model has high fire power and no coke oil, and can completely obtain the invention purpose of using straws which are not pulverized as the fuel of the straw gasifying furnace.

Description

Stalk gasifier

Technical field

The utility model relates to a kind of gas furnace, especially a kind of stalk gasifier.

Background technology

As everyone knows, since beginning to utilize this technology of gasifying stalk generation combustion gas to promote, the gasification furnace listing of a lot of structures of all kinds is successively arranged, but existing firewood gasification furnace ubiquity tar content height, the burning difficulty, firepower is little, and the large and small, thick, thin of faggot must use in collocation, especially can not use separately without stalk, the straw the pulverized defectives such as use that directly act as a fuel, be unfavorable for of the penetration and promotion of this product in the rural market.

The utility model content

The purpose of this utility model is to provide for overcoming the deficiencies in the prior art that a kind of firepower is big, no tar, can use untreated powder cutted straw, stalk to make the stalk gasifier of fuel fully.Concrete technical scheme is: stalk gasifier is by body of heater, bell, blast pipe, the secondary air supply pipe, grate, ash hole, compositions such as hot water interlayer, the top of blast pipe exceeds grate in the body of heater, and its top is provided with an aerofoil that goes out that has a plurality of ventholes, affixed one first air supply pipe on the furnace body inside wall, there is a gap on its top apart from the body of heater top, grate is passed in its underpart, also is fixed with a secondary air supply pipe on the furnace body wall, and its import is positioned at the grate below.

Aerogenesis quality when guaranteeing that fuel is the stalk do not pulverized, straw, the spacing dimension that goes out aerofoil and grate is 200-350mm.

For convenient faggot in the body of heater is depressed, be socketed with a compressing rod on the bell.

For ease of the first air supply pipe of cleaning and dredging, the body of heater top is provided with the hole, is connected with a screw in the hole.

For conveniently utilizing the hot water interlayer, hot water interlayer top is provided with water intaking valve, and the bottom is provided with outlet valve.

When using the utility model stalk gasifier, earlier air inlet pipe and air blast are connected, be connected gas appliance again after gas secondary air supply pipe and the gs-oil separator connection.Then fuel such as stalk, straw are invested in the body of heater, light with kindling material, start air blast and make its burning, with compressing rod the fuel in the body of heater is compressed then, fuel just produces combustion gas under not clean-burning situation, enter from first air supply pipe upper end import, come out from the lower end after the secondary air supply pipe is defeated by the gas appliance use.

From the technical solution of the utility model as can be seen, because air supply opening is positioned at the middle and lower part of body of heater, straw, the stalk without pulverizing that adds has sufficient charge space to come closed gas, add first air supply pipe and be arranged in body of heater, tar ingredients in the combustion gas production process is fully vaporized in first air supply pipe, basically there is not tar ingredients to enter gas appliance, it is big to have reached the utility model firepower fully, no tar can use untreated powder cutted straw, stalk to make the goal of the invention of the stalk gasifier of fuel fully.
