REGENERATIVE BOILER REGENERATION SURFACE DEVICE

FIELD: heating equipment. SUBSTANCE: group of inventions relates to regenerative boiler device. Device comprises a furnace for combustion of waste liquor and a flue gas duct， comprising vertical channels of flue gas， some of them are equipped with heat recovery units for heat recovery from flue gases. Flue gas channel first after the furnace is equipped with a heater and one of the following heat recovery units: an economizer or a boiler accumulator. Heater and second heat recovery unit are located one after another in horizontal direction of flue gas inlet so that in flue gas channel flue gas flows in vertical direction from top to bottom and simultaneously heats heater and second heat regeneration unit. According to the other device， the heater heat regeneration elements and the second heat regeneration unit are located one next to the other in the direction， which is transverse to horizontal direction of flue gas inlet. EFFECT: technical result is creation of device for heat recovery from flue gases formed during spent liquor combustion. 10 cl， 5 dwg

技术领域：加热设备。
本系列发明涉及蓄热式锅炉装置（regenerative boiler device）。该装置包括废液焚烧炉膛，以及烟气通道（flue gas duct），该烟气通道包含多段立式烟气通道，其中部分通道配置有烟气余热回收单元（heat recovery unit）。
炉膛后的首个烟气通道配备有加热器，以及下述二者之一的余热回收单元：省煤器（economizer）或锅炉蓄热器（boiler accumulator）。加热器与第二余热回收单元沿烟气入口的水平方向依次排布，使得烟气在烟气通道内自上而下垂直流动，并同时对加热器及第二余热回收单元进行加热。
针对另一实施方式的装置，加热器的换热元件与第二余热回收单元沿与烟气入口水平方向相垂直的方向相邻布置。
技术效果：开发出一种可回收废液焚烧过程中产生的烟气余热的装置。
