Waste Heat Recovery Special Boiler
Comprehensive Utilization Thermal Energy with 18,000 Nm³/H Processing Capacity
Product Overview
This specialized boiler is engineered for high-temperature flue gas containing molten salt generated from waste liquid and gas incineration in chemical plants. Utilizing a five-stage cascade temperature control system, it ensures stable transformation from molten state to solid ash through graded treatments including castable protective layers, cavity slow cooling, and enhanced heat exchange.
The system maintains high temperatures in the first stage to ensure continuous molten salt slag discharge, while precisely controlling middle stage temperatures below the ash melting point to prevent coking. The final stage integrates evaporator, superheater, and economizer components to efficiently recover waste heat and significantly reduce exhaust temperatures.
