Coal gas small furnace of energy-saving durable type fuel generation furnace for glass tank furnace

Abstract

The invention relates to a coal gas small furnace of an energy-saving durable type fuel generation furnace for a glass tank furnace, which solves the problems of short service life and low heat efficiency of the prior small furnace. The coal gas small furnace of the energy-saving durable type fuel generation furnace for the glass tank furnace comprises longitudinal passages which are in the shapeof a horn mouth, comprise a bottom plate, two side walls and a top wall and have small fronts and big backs, wherein the middle parts of the longitudinal passages are provided with tongues which are connected with the two side walls and extend from the back end to the front end, and at least one of an upper longitudinal passage and a lower longitudinal passage which are separated by the tongues comprises a plurality of transverse juxtaposed sub-passages separated by vertical partition walls. A distance among the tongues, the front ends of the vertical partition walls and the front ends of thelongitudinal passages is 0-800 millimeters. An inlet between the tongues at the back ends of the longitudinal passages and the top wall is communicated with a coal gas regenerative chamber of a generation furnace, and an inlet between the tongues and the bottom plate is communicated with a combustion-supporting air regenerative chamber. The invention has the advantages of little possibility of burning out, long service life, high heat efficiency and good energy-saving effect and is more beneficial to downward thermal radiation, a high-temperature combustion area moves to a glass melting tank forwards, and fuel gas is mixed fully.

Description

technical field [0001] The invention relates to a glass pool furnace, in particular to an energy-saving and durable generator gas small furnace for the glass pool furnace. Background technique [0002] The generator-fired gas small furnace (or pre-combustion chamber) used in the glass pool furnace is connected to the glass melting pool at the front end and the regenerator at the rear end; the generator-fired gas furnace is actually a small furnace that mixes gas and combustion-supporting air. The rear end of the regenerator is divided into upper and lower two ventilation channels by the tongue (the upper layer is an air channel, and the lower layer is a gas channel), and the front end of the glass melting tank is a fire channel without a tongue; the former is used to conduct Fuel gas, the latter is used to mix and ignite the two, and then spray into the glass melting pool to heat the glass material in the pool. Wherein the distance from the front end of the tongue to the fr...

AI Technical Summary

Problems solved by technology

Through the long-term observation and research of the present invention, it is found that the wall of the pre-combustion chamber is easily burned out, and the service life is often far lower than the design standard; in addition, part of the heat of the flame is not used on the glass material that should be heated, but is used on the glass material that should not be heated. On the wall of the preheating chamber, of course, energy will be wasted
