Abstract

The invention relates to the technical field of waste heat recycling equipment, in particular to a condensation type float bed energy-saving dust-and-emission-reducing multipurpose boiler which comprises a steam generator, a hot water generator and a condensation type float bed energy-saving dust-and-emission-reducing device. A smoke inlet of the steam generator is connected with a smoke pipeline. A smoke outlet of the steam generator is connected with a smoke inlet of the hot water generator through a pipeline. A smoke outlet of the hot water generator is connected with a smoke inlet of the condensation type float bed energy-saving dust-and-emission-reducing device through a pipeline. A smoke outlet of the condensation type float bed energy-saving dust-and-emission-reducing device is connected with a chimney through a pipeline. The steam generator and / or the hot water generator are at least above one level respectively. Compared with the prior art, sensible heat and latent heat in the smoke can be fully utilized, the heat recycling efficiency is greatly improved, heat recycled from waste heat can produce steam or hot water with different pressure and thus, the content of smoke, dust, sulfides and oxynitrides in the smoke can be effectively lowered and the aims of saving energy, reducing dust and reducing emission can be truly achieved.

Description

[Technical Field] [0001] The invention relates to the technical field of waste heat recovery equipment, in particular to a condensing floating bed energy-saving, dust-reducing and emission-reducing multi-purpose boiler. [Background technique] [0002] A large part of energy equipment is obtained by burning fuel, such as industrial boilers, steel mill blast furnaces, annealing furnaces, lime calciners, cement furnaces, glass furnaces, etc. In these devices, flue gas emission is the main heat loss and pollution source. The higher the emission temperature, the greater the heat loss. In the flue gas emitted, there is not only the fuel's own moisture, but also smoke, sulfide, nitrogen oxide and H 2 O. In order to prevent steam condensation and corrosion, the flue gas discharge temperature is generally above 100°C. At this time, the steam will not condense and is overheated. The sensible heat and latent heat of the steam in the flue gas will be discharged into the atmosphere along wit...
