An ultra-high temperature and ultra-high pressure gas boiler and its auxiliary equipment installation method

Abstract

A method for installing an ultra-high-temperature, ultra-high-pressure gas boiler and its auxiliary equipment, comprising the following installation steps: boiler foundation marking, boiler steel frame installation, drum installation, air preheater installation, economizer installation, water wall combination, front Water-cooled wall installation, right water-cooled wall installation, rear water-cooled wall installation, left water-cooled wall installation, wall-wrapping team, wall-wrapping installation, superheater installation, reheater installation, body pipeline installation, guard plate furnace wall installation, its features That is, the installation of the boiler steel frame is the installation of separate parts, and the boiler steel frame is a three-dimensional frame structure. The steel frame is divided into different sub-package parts through the uprights and then assembled and installed as a whole. The beneficial effects of the present invention: reduce high-altitude operations, Protect the life and property safety of the staff, improve work efficiency, reduce working hours, shorten the construction period, the installation accuracy can be controlled at any time, improve the accuracy of the sub-assembly parts of the steel frame, improve the assembly accuracy after the steel frame is assembled, and ensure the follow-up installation of boilers, etc. installation accuracy.

Description

technical field [0001] The invention relates to the field of boiler installation, in particular to an installation method of an ultra-high temperature and ultra-high pressure gas boiler and its auxiliary equipment. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. When the boiler burns different fuels, it is called the boiler of this kind of fuel or the mixed-fired boiler of some two fuels. [0003] A gas boiler is an energy conversion device that burns coal gas as the main fuel to generate steam. The gas types of the gas boiler are mainly divided into coke oven gas, blast furnace gas, and converter gas. According to the different energy conversion rates, the fuel configuration of the gas boiler The ratio is also different. Converter gas can...
