Abstract

A boiler for heating saturated steam comprises a burning device (1), a saturated steam low-temperature superheater (4) above the burning device (1), a saturated steam high-temperature superheater (5) above the saturated steam low-temperature superheater (4), an evaporator (7), a coal economizer (8) and a steam packet (6). An attemperator (9) and an optional fan (11) serving as auxiliary equipment are arranged at an outlet of the saturated steam low-temperature superheater (4). The burning device (1) is composed of a burner (101), a boiler wall (102) and a burning chamber (103). According to the gas boiler for heating saturated steam, low-quality saturated steam can be heated into high-quality superheated steam, high-temperature exhaust smoke after heating the saturated steam is fully utilized, the thermal efficiency is high, and the energy saving effect is good. The boiler is simple in structure, no air preheater is arranged, and a wind and smoke pipeline is simple. By means of the thermal-insulation burning chamber, burning is stable.

Description

technical field [0001] The invention relates to a gas boiler, in particular to a gas boiler for heating saturated steam and a method for heating saturated steam to obtain superheated steam. Background technique [0002] The metallurgical industry produces a large amount of saturated steam in the production process. This kind of saturated steam is mostly used for production or domestic use because of its low energy quality. For example, it is used for heating in production, or as steam for purging; it is used for bathhouses, canteens and heating in daily life. However, these amounts are very small, and most of the saturated steam is directly discharged, which is wasted. [0003] With the development of technology, the requirements of energy conservation and emission reduction policies and the needs of enterprises to reduce energy consumption, the development and utilization of low-grade waste heat has now begun. Such as screw expansion generators and saturated steam genera...
