Novel boiler

Abstract

The invention discloses a novel boiler, which comprises a boiler main body, and the furnace wall of the combustion chamber in the boiler main body is successively composed of a refractory layer, a thermal insulation layer and a heat exchange layer from inside to outside. The advantage is that unlike traditional boilers that exchange heat in the combustion chamber, this application sets an insulation layer on the outside of the refractory layer so that the heat in the combustion chamber will not be easily lost, effectively ensuring the temperature in the combustion chamber, so that it can be used under high temperature conditions. The organic macromolecules that can be cracked and burned can be fully burned, and the heat exchange layer outside the insulation layer will fully absorb the heat emitted by the insulation layer. While ensuring the heat conversion efficiency, it improves the combustion efficiency of the boiler and the combustion utilization of coal. At the same time, it reduces the content of combustibles in the flue gas, reduces harmful emissions, and greatly improves the energy-saving and emission-reduction effects of the boiler.

Description

Technical field: [0001] The invention relates to a boiler, in particular to a novel boiler. Background technique: [0002] Coal and petrochemical organic fuels are complex organic macromolecules, some of which require higher temperatures for cracking and combustion. [0003] The total efficiency of the boiler is determined by two factors: combustion efficiency and heat conversion efficiency, namely: total boiler efficiency = combustion efficiency × heat conversion efficiency. [0004] At present, boilers usually only focus on heat exchange, that is, a heat exchange layer is directly installed on the inner wall of the main combustion chamber for heat exchange, or a heat exchange layer is installed inside or outside the refractory layer on the inner wall of the main combustion chamber for heat exchange, so that the combustion chamber The furnace temperature is very low, causing the organic macromolecules that need to be cracked and burned under high temperature conditions can...
