Self-adaptive intelligent waste heat boiler

Abstract

The invention discloses an adaptive intelligent waste heat boiler, which comprises an upper front smoke box, an upper drum and an upper rear smoke box which are connected in sequence, and a waste heat flue gas inlet is arranged on the upper front smoke box, and an upper boiler is arranged inside the upper drum. The convection pipe is provided with a liquid inlet on the upper drum, and a waste heat flue gas outlet is located on the upper rear smoke box. A lower drum is also provided outside the upper drum, and the lower drum and the upper pot The drum is connected; the lower drum is provided with a supplementary combustion mechanism for heating it. Based on the post-combustion waste heat boiler, and aiming at the medium and low temperature waste heat flue gas, through system monitoring and boiler development, the post-combustion system and waste heat boiler are integrated to improve the overall operation stability of the waste heat boiler, reduce the requirements of waste heat sources, and effectively Reducing the floor space also enables the waste heat boiler control system to adapt to intelligent control.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a waste heat boiler that enables the control system of the waste heat boiler to be self-adaptive and intelligently controlled through system monitoring and boiler development. Background technique [0002] Waste heat boiler is a boiler that uses waste heat to generate steam. Waste heat recovery and energy saving can effectively reduce environmental pollution and respond to the national call for energy conservation and emission reduction. There are many forms of waste heat boilers, but most of them are traditional flue type (see figure 1 ) including (1) flue interface, (2) upper drum, (3) convection tube, (4) lower drum, (5) serpentine tube economizer. Its structure can recover high-temperature flue gas, but the disadvantage is that it consumes a lot of metal and occupies a large area. or smoke tube waste heat boiler (see figure 2 ) including (1) flue interface, (2) ...

AI Technical Summary

Problems solved by technology

At present, waste heat boiler technology at home and abroad has been developed for many years, but it has been unable to meet the current increasingly stringent environmental protection requirements, and the requirements for waste heat sources are very high. If the waste heat source is not stable enough, the system's initial start-up source is insufficient, etc., it will cause the waste heat boiler to work. Unstable, which affects steam volume and steam quality
