Waste Heat Recovery Water Tube Steam Boiler Precise Thermal Classification

The modular boiler adopts a multi-stage heat exchange structure featuring a hierarchical system integrating evaporators and economizers, along with a steam temperature control unit. Through precise thermal classification design, waste heat is efficiently recovered and exhaust gas temperature is significantly reduced. The advanced ash cleaning system combines shock wave and sound wave dual-mode technology with a modular open-air layout to effectively suppress dust accumulation and reduce heat transfer efficiency attenuation, ensuring long-term efficient operation.

This modular boiler is specially customized for high-temperature, high-dust scenarios in refineries. It features a five-stage evaporator + four-stage economizer cascade heat exchange system (flue gas flow rate 297,990 Nm³/h, exhaust temperature ≤190℃), achieving a 30% increase in waste heat recovery efficiency. Through coordinated control of the two-stage superheater + water spray desuperheater (steam temperature accuracy ±2℃), it ensures continuous stable output of 11MPa/520℃ high-pressure steam. The innovative shock wave/sonic wave dual-mode soot blowing system (ash cleaning coverage ≥95%) combined with modular open-air layout reduces heat transfer efficiency attenuation to <5%, adapting to 7×24-hour full-load refinery operations.

This modular water tube boiler enables coordinated utilization of high calorific value fuel and industrial waste gas through multi-stage waste heat cascade recovery architecture. The system increases flue gas waste heat utilization by 30% and features an integrated evaporator-superheater-economizer three-stage heat exchange system combined with intelligent PID steam temperature control algorithm. Self-cleaning spiral heat exchange tube groups with nano-coating + shock wave soot blowing dual-effect anti-ash deposition technology and modular quick-installation design (single module replacement under 3 hours) suppress long-term operation heat transfer efficiency attenuation to less than 5%. Ideal for biomass power generation, chemical parks, and other scenarios requiring efficient recovery, precise temperature control, and long-term stability.

Especially suitable for installation environments with limited space, such as industrial production steam supply, where rapid response to load changes is required.
