Fuel gas, fuel oil and fused salt integrated steam boiler

Abstract

The invention discloses a fuel gas, fuel oil and fused salt integrated steam boiler. The fuel gas, fuel oil and fused salt integrated steam boiler is mainly composed of a first fused salt groove, a second fused salt groove, an insulating layer, a combustion cavity, a combustor, an air preheating recoverer, a chimney, a waste heat recycling water tank, a high-pressure plunger pump, a steam pipe coil, a steam header, a steam generator body and a high-pressure spraying device. The fuel gas, fuel oil and fused salt integrated steam boiler has the advantages that firstly, steam mist jetting is adopted for water feed, the heat exchange area is increased, and the heat efficiency is improved; secondly, the temperature and the pressure of the steam can be adjusted, incrustation is avoided, the service life of the boiler is prolonged, boiler waste water is avoided, and a large number of water resources are saved; and thirdly, waste heat is recycled and utilized completely.

Description

technical field [0001] The invention belongs to a boiler and a steam generator. Specifically, it is a gas-fired, molten-salt integrated steam boiler. Background technique [0002] The whole world has been studying how to improve the thermal efficiency of the boiler body to save natural resources. Generally, it is the research on the manufacturing materials and the way of fuel entry, and then gradually produces subcritical, supercritical, and ultra-supercritical. Boiler, but it has not broken through the basic structure of the boiler and the way of steam water supply. At present, it still stays in the state of the traditional heating mode and the steam production mode of boiling bubbles. [0003] Traditional boilers are bulky and complex in structure, the steam water supply method is backward, the boiler startup and shutdown consumes a lot of energy, the operation is complicated and takes a long time, the selection and application of heat transfer medium is unreasonable, and...

AI Technical Summary

Problems solved by technology

[0006] The invention solves the problem of backward water supply mode and steam production mode of traditional boilers for hundreds of years, direct heating of heat transfer medium pipes by heat carrier furnaces, large heat loss of heat transfer medium, large amount of heat transfer medium, incomplete waste heat recovery, poor steam quality, and bulky boiler equipment , waste of consumables, etc.
