基于SRF特性及SRF焚烧对锅炉的影响分析，提出650t/d SRF循

SRF and SRF characteristics based on the boiler Incinerator analysis, 650t / d SRF circulating fluidized bed incinerator particular embodiment, the feed points by taking, multi-point slag, furnace design large cross-section a low flow rate, the separation device outlet is provided flue burnout air chamber, the convection heating surface disposed in-line pitch, the high-temperature superheater disposed downstream of the flue gas, external air preheater, flue gas recirculation, cooled ash hopper and a lower hopper outlet disposed auger and other measures to achieve the highly efficient and stable SRF incineration. The combustion system for a combustion stability requirements, supplementary bed material, the outlet pressure of the furnace, a secondary air amount adjusting key operating differential pressure and other operating parameters of control layers recommendations.

Based on the sRF characteristics and the analysis of the impact of SRF incineration on the boiler, the concrete embodiment of 650t/d SRF circulating fluidized bed incineration boiler is put forward, and by adopting two-point feeding, multi-point slag discharge, low flow rate design of large cross-section of furnace, separation device outlet setting air flue ember Room, convection heat-heated surface large pitch arrangement, high temperature superheater and flue gas flow arrangement, air preheater external, flue gas recycling, water-cooled gray bucket and export ash bucket lower arrangement spiral conveyor and other measures to achieve the SRF's efficient and stable incineration disposal. In view of the stable combustion requirements of combustion system, the key operating parameters such as supplementing bed material, furnace outlet pressure, one or two air volume adjustment, material layer differential pressure and other key operating parameters are proposed.

Based on the analysis of SRF characteristics and the influence of SRF incineration on the boiler, 650T / D is proposed The specific implementation scheme of SRF circulating fluidized bed incineration boiler adopts two-point feeding, multi-point slag discharge, large section and low flow rate design of furnace, air flue combustion chamber set at the outlet of separation device, large section and sequence arrangement of convection heating surface, high-temperature superheater and flue gas downstream arrangement, external arrangement of air preheater, flue gas recycling, water-cooled ash hopper and spiral conveyor set at the lower part of outlet ash hopper, etc Measures are taken to realize efficient and stable incineration disposal of SRF. According to the requirements of stable combustion of combustion system, some suggestions are put forward for operation control of key operation parameters, such as supplementary bed material, furnace outlet pressure, primary and secondary air volume regulation, material layer differential pressure, etc.
