Efficient, energy-saving and environment-friendly gas/oil steam boiler

Abstract

The invention relates to the technical field of boilers, and particularly discloses an efficient, energy-saving and environment-friendly gas / oil steam boiler which comprises a boiler body. The boilerbody comprises a hearth, a heat exchange unit, a steam pocket and a boiler wall, wherein the heat exchange unit comprises a water cooling wall, first heat exchange tubes and a second heat exchange tube, and the water cooling wall is longitudinally arranged to divide the hearth into a combustion area and a convection area; the first heat exchange tubes are vertically arranged along the interfaces on the two sides of the combustion area and the interface of the convection area; the second heat exchange tube is vertically arranged in the convection area; the lower ends of the first heat exchangetubes and the second heat exchange tube are gathered at a longitudinal lower collecting tube, and the upper ends of the first heat exchange tubes and the second heat exchange tube are gathered at a longitudinal upper collecting tube; the steam pocket is arranged outside the hearth and communicates with the upper part of the upper collecting pipe; and the boiler wall wraps the hearth and the steampocket. Multi-stage heat exchange can be conducted, heat exchange can be enhanced, steam pressure adjustment is better facilitated through adjustment of the front water volume and the rear water volume, and meanwhile the burst risk caused by violent steam pressure can be avoided.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a high-efficiency, energy-saving and environment-friendly gas / oil steam boiler. Background technique [0002] With the rapid development of social economy, boilers are widely used in modern industry, electric power and people's life as process equipment for producing heat and power, and gas-fired boilers satisfy people's requirements for environment, safety, Automation requirements, so many projects have adopted gas boilers as their heating equipment. [0003] Gas boiler includes two systems of gas combustion equipment and boiler body. Gas combustion equipment mainly refers to the furnace and burner, and also includes other equipment related to the combustion process. Its main function is to pass a certain amount of combustible gas and air into the combustion equipment, and convert chemical energy into thermal energy through the combustion of combustible gas. , to provide conti...
