Waste heat boiler

The waste heat boiler consists of a drum, a movable fume hood, a flue at the furnace mouth section, an oblique section of flue, an oblique section of flue, the last section of flue, the last two sections of flue, feeding pipe (down feed chute) tank, oxygen It is composed of muzzle, nitrogen sealing device and nitrogen sealing plug, manhole, differential pressure taking device, flue support and hanger, etc. The waste heat boiler is divided into six circulation loops. Each circulation loop is composed of downcomer and riser. The feed water of each section of the flue is introduced from the drum through the downcomer to the lower header of each flue, and then enters each heating surface. The steam generated after the heating surface enters the inlet header, and then is introduced into the drum through the riser. All flues are connected by flanges.

Introduction

Waste heat boiler, as the name implies, refers to a boiler that uses waste heat from various industrial processes, waste heat or waste liquid and the heat generated by the combustion of combustible substances to heat water to a certain temperature. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with flue box and flue waste heat recovery are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery.
