Burning utilizing method for super low concentration combustible gas

Abstract

The method is in use for assistant burning of combustion equipment by using combustible gas in ultralow concentration (exhaust gases from coal mine with firedamp less than 1%, marsh gas of containing combustible gas in ultralow concentration, and combustible gas unable to be ignited by small fire generated from procedures of chemical engineering metallurgy). Through pipe, the said combustible gas transported to air inlet of combustion equipment is as combustion-supporting air and assistant fuel of main fuel to enter into firebox of combustion equipment to carry out burning. Features are: simple technique and equipment, reliable, reasonable design, taking full advantage of using energy, and environmental protection.

Description

technical field [0001] The invention relates to a combustible gas combustion method, in particular to a combustion utilization technology of an ultra-low concentration combustible gas, and belongs to the technical field of energy conservation and environmental protection. Background technique [0002] Ultra-low concentration combustible gas, the main methane concentration is less than 1%, coal mine ventilation exhaust gas, biogas generation and other ultra-low concentration methane, and various chemical and metallurgical processes that cannot be ignited with a small flame at room temperature. flammable gas. In the past, these combustible gases were mainly discharged into the atmosphere. Due to the huge amount, it caused a serious waste of resources. At the same time, some greenhouse gases discharged also caused serious environmental damage. Because these ultra-low concentration combustible gases are difficult to be directly burned as the main fuel, the development of their ...
