Abstract

The invention discloses an energy-saving coal gasification reacting furnace and method. The energy-saving coal gasification reacting furnace comprises a reacting furnace body and a steam supply cavity, wherein the steam supply cavity is arranged on one side of the reacting furnace body, and the outside of the reacting furnace body is provided with a spiral heat exchange tube which is provided witha water pumping unit; the top of the steam supply cavity is provided with a steam discharging pipe which is provided with a steam conveying unit, a gas flow metering unit and a pipe opening and closing unit; the inside of the steam supply cavity is provided with a snake-like heat exchange pipe, the end portion of the snake-like heat exchange pipe is provided with an internal joint, the outside ofthe internal joint is provided with a connecting ring fixed onto the side surface of the steam supply cavity, a sealing cover is connected in a sleeve mode outside the connecting ring, and the innerwall of the steam supply cavity is provided with a heating element. The energy-saving coal gasification reacting furnace avoids an idle state of the reacting furnace body to maximize energy-saving effects, and meanwhile, is reasonable in design and high in practicality.

Description

technical field [0001] The invention relates to the technical field of coal gasification, in particular to an energy-saving coal gasification reaction furnace and a method. Background technique [0002] The patent application publication number CN 206955962U discloses a high-efficiency reaction furnace for coal gasification, which can greatly improve the energy utilization efficiency of the equipment, reduce production costs, and achieve the purpose of energy saving and environmental protection by adopting a preheating recovery device. However, there are still some shortcomings in the actual implementation of this technical solution. For example, there is no independent oxidant heating equipment. In order to provide heat during the initial operation of the equipment to make the oxidant, that is, water, heated and evaporated into water vapor, it is necessary to make the equipment idle for a certain period of time, and the equipment idles. At the same time, it will consume mor...
