Abstract

The invention includes a boiler body having radiation and convection heating surfaces. The radiation heating surface is a cylinder body coiled by a single radiation heating tube and the convection heating surface is a coiled tube bundle coiled by a single convection heating tube. One end of the radiation heating tube is used as a water inlet and the other end is in communication with a discharging tube of the radiation heating pipe. The discharging tube of the radiation heating tube is in communication with the convection heating tube. The boiler body is made up of three layers. The inlayer is a corrugated plate made of alumina silica refractory ceramic fibre by pressing, the middle layer is a insulation one and the other layer is an infrared-proof coating.

Description

technical field

[0001] The invention belongs to an oilfield high-efficiency thermal recovery system, in particular to a once-through boiler system with supercritical pressure and advanced water treatment technology. Background technique

[0002] According to thermodynamic analysis, in order to improve the power generation efficiency of thermal power plants and reduce power generation costs, one of the main methods adopted is to increase the parameters (pressure, temperature, etc.) of the outlet steam of steam boilers (also known as steam generators) to improve their working ability. . At present, many scholars at home and abroad are working on the research and application of supercritical and ultra-supercritical power generation technology. Correspondingly, all supercritical pressure steam boilers are used in thermal power plants so far. During their operation, problems must be solved Its steam generator has problems such as pulsation of working fluid flow in the heating tu...
