AI Technical Summary

Technical Problem

Existing furnaces suffer from incomplete combustion, heat loss, and heat concentration during combustion, especially for solid fuels such as coal and firewood, making it difficult to ensure complete combustion and full heat release.

Method used

A fuel combustion furnace structure was designed, including a combination of guide plates and gasification holes. The guide plates are arc-shaped and are evenly spaced along the conical surface to form guide grooves. The gasification holes gradually decrease in diameter on the arc surface. Combined with air inlets and filters, secondary oxygen supply and air mixing are achieved, promoting complete combustion and concentrating heat.

Benefits of technology

The design of the guide plate and gasification holes enables complete combustion of fuel and concentration of heat, reduces heat loss, meets the needs of various solid fuels, and improves combustion efficiency and thermal energy utilization.
