Abstract

The invention provides a boiler circulation heat conduction structure. A heat gathering cavity, heat exchange pipes and a circulation pipe are included. The part, above a heating device, at the bottomof a boiler body is provided with the heat gathering cavity, and heat conduction media are arranged in an inner cavity of the heat gathering cavity. The heat gathering cavity communicates with at least one heat exchange pipe, the heat exchange pipes penetrate through the boiler body and communicate with the circulation pipe, and the circulation pipe communicates with the heat gathering cavity. The circulation pipe is provided with a circulation drive device. Through the arrangement of the structure of the heat gathering cavity, the structure of a double-layer water cavity in the prior art iseliminated, and the machining difficulty is lowered; by adoption of the common cylinder and circular-roof boiler structure, the pressure bearing capability of a boiler can be better improved, and themachining cost is greatly reduced. Through the arranged heat gathering cavity, flames of the heating device can be centralized at the bottom of the boiler body, and the fuel utilization rate is increased. In the preferable scheme, a circulation pump is arranged so that the heat exchange pipes can be rapidly utilized for conducting heat to water in the boiler body, and heat generated during combustion of the heating device is further sufficiently utilized.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a boiler circulation heat conduction structure. Background technique [0002] Existing boiler equipment all adopts heating device to heat the boiler body so that the water in the boiler body is heated to generate water vapor. With the rise of energy prices and the improvement of environmental protection requirements, it is necessary to reduce carbon emissions and improve energy efficiency. [0003] Chinese patent document CN 101871688 A describes a heat pipe boiler. This heat pipe boiler includes a cylindrical pot shell and a cylindrical furnace inside the pot shell. A furnace body water chamber is formed between the furnace gall and the pot shell. , a furnace is formed inside the furnace, and an inner water box is arranged on the upper part of the furnace, and the inner cavity of the inner water box communicates with the water chamber of the furnace body through a connecting pip...
