Device for thermal substance separation for integrated fuel gas-fuel oil salt-melting boiler

Abstract

The invention discloses a device for thermal substance separation for an integrated fuel gas-fuel oil salt-melting boiler. The device is mainly composed of an expansion groove, a salt-melting groove, a salt-melting guide tube, a heat-insulation layer, a combustion cavity, an air preheating recoverer, a waste heat recovery water tank, a combustor, a high-pressure plunger pump, a steam coiled tube, a steam manifold, a steam generator main body, a high-pressure spraying device, a dust removal limewater pool, a chimney, a solid-state substance conveyer, a liquid-state substance conveyer, a substance decomposition coiled tube, a cyclone separation tower, a decomposition reduction chamber and a cooling tower. The device disclosed by the invention has the following advantages: with the adoption of the high-pressure spraying device, 1) injection steam fog is generated to supply water, and a heat exchange area is expanded, thus the heat efficiency is increased; 2) the high-pressure spraying device is free from scale and boiler waste water; and 3) the high-pressure spraying device is complete in waste heat recovery and utilization and complete in emission collection treatment.

Description

technical field [0001] The invention relates to a boiler, a steam generator and a heat separation device. Specifically, it is a device for thermally separating substances in a gas-fuel-fuel molten-salt integrated 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 has not broken through the basic structure of the boiler and the way of steam water supply. Currently, it is still in the state of the steam production mode of boiling bubbles, and the fuel combustion, ignition, and waste heat recovery are not ideal, and the investment in the treatment and collection of emissions is huge. , poor effect, etc. [0003] Traditional concentration and drying equipment has complex and multi-stage processes...
