Abstract

PURPOSE: To reduce NOX to N and make it pollution-free at the time of removing the contained NOX from combustion exhaust gases of boilers, etc., by adding ethers to the exhaust gases and heating the gases.
CONSTITUTION: Ethers such as methyl ether, ethyl ether, methyl ethyl ether are added in the form of liquid or gas with combustion exhaust gas, air, etc. as a carrier into combustion exhaust gases of boilers, gas turbines, etc. These mixed exhaust gases are heated to 250W700°C in the presence of oxygen to reduce NOX to pollution-free NO. The combustion exhaust gases are released as pollution-free gas without containing any NOX, and do not become the cause for environmental pollution.
