AI Technical Summary

Technical Problem

Existing combustion devices struggle to adjust the air-fuel ratio within a predetermined range while precisely controlling heat output, especially when fuel composition fluctuates.

Method used

A combustion device that controls the amount of combustion air based on the theoretical air requirement per unit of calorific value of the mixed fuel, using a control system to adjust the air-fuel ratio and heat output, incorporating a detection system to detect abnormalities in air supply, and an air-fuel ratio detection system to maintain a stable combustion state.

Benefits of technology

The system ensures accurate adjustment of air-fuel ratio and heat output, maintaining a stable combustion state even with fuel composition fluctuations, and provides precise detection of air supply abnormalities.

Abstract

The objective is to provide a combustion device that can maintain an appropriate combustion state by precisely adjusting the heat output to the target while adjusting the air-fuel ratio within a predetermined range, even when the fuel composition fluctuates. [Solution] A combustion device for burning a mixed fuel, comprising a control means for controlling the amount of combustion air supplied based on the theoretical amount of air per unit of the calorific value of the mixed fuel.
