Abstract

The invention discloses a gas-fired boiler for overheating external steam, and relates to the technical field of gas-fired boilers. The gas-fired boiler comprises a boiler body and a heating box, wherein a ventilation pipe is arranged on the side wall of the boiler body in a penetrating mode, and a purification mechanism is arranged on the ventilation pipe; the side wall of the ventilation pipe penetrates through the side wall of the heating box, the end part of the ventilation pipe communicates with the side wall of the boiler body, and a heater is arranged in the heating box and tightly attached to the side wall of the ventilation pipe; and the purification mechanism comprises a sealing piston connected to the side wall of a purification box in a penetrating and sliding mode, a mountingblock is fixedly connected to the side wall of the sealing piston, and the side wall of the mounting block abuts against the inner side wall of the purification box. Through cooperative use of the ventilation pipe, the boiler body, the heating box and the heater, the ventilation pipe can become a power generation source in the heating process, so that cyclic utilization of energy is achieved.

Description

technical field [0001] The invention relates to the technical field of gas boilers, in particular to a gas boiler for superheating external steam. Background technique [0002] In the metallurgy, building materials, petroleum, and chemical industries, there are a large number of waste heat resources with a temperature lower than 400°C, but some waste heat resources are very unstable. With the periodic changes in the process, it is difficult to use waste heat; Exhaust gas enters the waste heat boiler, which can produce low-pressure saturated steam, but the steam production is unstable, and the scope of use is greatly limited. For example, low-pressure saturated steam is used for power generation of turbogenerators, which not only has low efficiency, large investment, and poor economic benefits, but the steam Unstable energy will also seriously affect the safe and reliable operation of turbogenerators. Therefore, the implementation of waste heat power generation for a large nu...
