AI Technical Summary

Technical Problem

Traditional corner tube boilers suffer from incomplete combustion, resulting in the emission of harmful gases such as unburned hydrocarbons and carbon monoxide, which reduces energy efficiency and increases environmental pollution.

Method used

A gasification combustion boiler was designed, comprising a gasification arch and a front ignition arch to form a gasification chamber. Flue gas undergoes secondary combustion in the gasification chamber, reducing the emission of incompletely combusted gases. The combustion efficiency is improved through the structural design of the gasification arch and the front ignition arch.

Benefits of technology

It improves thermal efficiency, reduces harmful gas emissions, lowers environmental pollution, and achieves a more efficient combustion process.

Abstract

The utility model relates to a gasification combustion boiler, and belongs to the technical field of boilers. The problem that fuel combustion of a traditional corner tube type boiler is insufficient is solved. Comprising a boiler body, a pipe frame, a fuel hopper and a chain grate stoker, and the boiler body is composed of membrane water cooling walls on the periphery and the top; the pipe frame is arranged on the periphery of the furnace body; the chain grate stoker is mounted at the bottom of the furnace body; the fuel hopper is mounted on the chain grate stoker; a partition wall water cooling wall is arranged in the boiler body and divides the interior of the boiler body into a hearth and a convection flue which are arranged front and back. A front ignition arch is arranged at the lower part of the front side water cooling wall of the boiler body; a rear arch is arranged at the lower part of the partition wall water-cooled wall; the gasification arch is arranged on the front side of the front ignition arch, and a gasification chamber is formed between the gasification arch and the front ignition arch; a smoke outlet window is formed in the upper portion of the front ignition arch, fuel generates combustible gas in the gasification chamber, the combustible gas and smoke enter the hearth through the smoke outlet window for secondary combustion, and the combustion efficiency of the fuel is improved.
