Coal-to-gas energy saving and environmental protection boiler

Abstract

The invention discloses a coal-to-gas energy-saving and environment-protecting boiler, comprising a water jacket furnace body; a gasifying burning chamber is arranged at one side in the water jacket body; a heat exchange chamber is arranged at the other side in the water jacket body; a grate is arranged at the bottom of the gasifying burning cavity; a refractory material gasifying chamber with an opening in the lower bottom is arranged at the grate; a refractory material burning chamber is arranged at the upper part of the refractory material gasifying chamber; a flame fuel gas channel is arranged around the refractory material gasifying chamber and the refractory material burning chamber and at the top of the refractory material burning chamber; a coal adding port is formed in the side surface of the upper part of the refractory material gasifying chamber; a flame fuel gas inlet is formed in the upper part of the refractory material burning chamber of which the side surface is provided with a fire passing port and a fire observing port. The coal-to-gas energy-saving and environment-protecting boiler is simple and reasonable in structure, full in gasification, fast in fire starting of the boiler, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a boiler, in particular to a coal-to-gas energy-saving and environment-friendly boiler. Background technique [0002] The coal-to-gas boiler is an energy-saving boiler that has been praised in recent years. Its working principle is that coal is dry-distilled in the coal-to-gas chamber under the condition of isolation from air and high temperature. The dry distillation chemical reaction process includes dehydration, pyrolysis, dehydrogenation, thermal condensation, Hydrogen, coking and other reactions. An important condition for coal dry distillation is high temperature. When the temperature of coal is higher than 100°C, the water in the coal will evaporate; when the temperature rises above 200°C, the crystal water in the coal will be released; The coal begins to soften and further forms a viscous colloid; at 400-500°C, most of the gas and tar are precipitated; at 450-550°C, thermal decomposition continues, and the residue grad...

Problems solved by technology

Since the heat of the water jacket furnace body is continuously taken away by the circulating water, it is difficult to form high-temperature carbonization conditions in the coal-to-gas chamber, resulting in insufficient coal carbonization and gasification, slow boiler ignition, low coal thermal efficiency, and floating particles in the discharged flue gas. Many, the soot discharged through the chimney will cause serious pollution to the environment
