Gas reburning energy-increasing environment-friendly boiler

Abstract

The invention relates to an energy-increasing environment-friendly boiler which performs cracking reaction on most dry water steam into combustible and combustion-supporting gas through high temperature generated by fire coal combustion by using dry steam of water, also decomposes the other small part uncracked dry water steam into combustible and combustion-supporting gas through a plurality of reactions in a high-temperature region. The combustible and combustion-supporting gas can be reburned in a combustion chamber so as to improve the thermal power. The boiler has two types of: 1, a gas reburning energizy-increasing hot-water boiler; and 2, a gas reburning energy-increasing steam industrial boiler. The two boilers have substantially same design principles that: the gas reburning energy-increasing hot-water boiler consists of a part which producing combustible and combustion-supporting gas part by using the dry water and a fuel combustion gas reburning energy-increasing part; and the gas reburning energizing steam industrial boiler also consists of a part which producing combustible and combustion-supporting gas part by using water vapor generated from the boiler and the fuel combustion gas reburning energy-increasing part. Due to the preparation of dry steam by using water vapor and increasing energy, the energy-increasing environment-friendly boiler has the advantages of greatly improving the energy utilization rate, saving the fire coal and reducing the environmental pollution.

Description

Technical field: [0001] The present invention relates to a boiler, in particular to a boiler that utilizes the dry steam of water to crack most of the dry steam into combustible and combustion-supporting gas through the high temperature generated by coal combustion, and a small part of the dry steam that has not been cracked passes through the high temperature zone. This reaction is also decomposed into combustible and combustion-supporting gas, which can be burned again in the combustion chamber to increase the thermal power of the energy-enhancing and environmentally friendly creative boiler. Background technique: [0002] The issue of energy and environmental protection is a major global issue that seriously restricts the development of our human beings. The current various combustion equipment generally has shortcomings such as unsatisfactory combustion efficiency and difficulty in meeting emission standards, which must be solved now. Numerous tests over the years have p...
