Burning head device of straw gasifier

Abstract

The invention discloses a burning head device of a straw gasifier, which comprises a cylindrical burning cylinder. A top surface of the cylindrical burning cylinder is provided with a fire outlet; the bottom end of the burning cylinder is connected with a gas inlet pipe; an air inlet pipe is connected to a side wall of the burning cylinder; a fire stop plate is horizontally arranged in the burning cylinder below an air inlet pipe port; a burning chamber is formed in the burning cylinder arranged between the fire stop plate and the air inlet pipe port; an annular fire-out gap is reserved between the outer peripheral edge of the fire stop plate and an inner peripheral wall of the burning cylinder; the height from the top surface of the fire stop plate to the fire outlet is 5-10cm; burning holes are centrally and symmetrically arranged on a plate surface of the fire stop plate; hole walls of the burning holes are rotary double-curved surfaces; the hole aperture of the central throat part of the burning hole is 5mm; flame guiding grooves are uniformly arranged at intervals on the outer peripheral edge of the bottom surface of the fire stop plate in the radial direction; the upper ends of the flame guiding grooves stretch to the position of the outer periphery of the top surface of the fire stop plate; the outer periphery of the fire stop plate is in an arc shape from bottom to top; and the annular fire-out gap is 2cm and the diameter of the fire stop plate is 10-18cm.

Description

technical field [0001] The invention belongs to the improvement of the structure of a straw gasification furnace, and relates to a combustion head device of a straw gasification furnace. Background technique [0002] The existing straw gasifier has been widely popularized and applied in the vast urban and rural areas of our country because of its environmental protection and non-pollution. The straw gasification furnace uses straw, fly ash, plastic and various combustible sundries as raw materials, and can produce high-quality gas under the condition of simmering, which can be used for people to boil water and cook. The gas contains components such as tar and water, which need to be removed in order to improve the cleanliness of combustion. However, the combustion head equipped with the existing straw stove often has the problem of insufficient combustion during use, and the dust such as ash in the combustion flame is directly discharged into the atmosphere, which not only ...

AI Technical Summary

Problems solved by technology

However, the combustion head equipped with the existing straw stove often has the problem of insufficient combustion during use, and the dust such as ash in the combustion flame is directly discharged into the atmosphere, which not only pollutes the environment, but also causes a large amount of heat loss, which needs to be improved urgently
