Waste Heat Recovery Water Tube Steam Boiler Precise Thermal Classification Low Exhaust Gas Temperature

Waste Heat Recovery Water Tube Boiler Precise Thermal Classification Low Exhaust Gas Temperature

Overview:
The modular boiler adopts a multi-stage heat exchange structure (a hierarchical heat exchange system integrating evaporators and economizers) and a steam temperature control unit (coordinated adjustment of two-stage superheaters + spray water desuperheaters). Through the precise design of thermal classification, the waste heat is efficiently recovered and the exhaust gas temperature is significantly reduced. Its 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 and efficient operation of the heating surface.

Product Introduction:

This modular boiler is specially customized for high-temperature and high-dust scenarios in refineries. It adopts a five-stage evaporator + four-stage economizer cascade heat exchange system (flue gas flow rate 297,990 Nm³/h, exhaust temperature ≤190℃), which can achieve a 30% increase in waste heat recovery efficiency; through the coordinated control of the two-stage superheater + water spray desuperheater (steam temperature accuracy ±2℃), it ensures the continuous and 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 a modular open-air layout can reduce the heat transfer efficiency attenuation rate to <5%, adapting to the 7×24-hour full-load operation of the refinery.

Advantages:

This modular water tube boiler realizes the coordinated utilization of high calorific value fuel and industrial waste gas through a multi-stage waste heat cascade recovery architecture (the utilization rate of flue gas waste heat is increased by 30%, and an integrated evaporator-superheater-economizer three-stage heat exchange system) combined with an intelligent PID steam temperature control algorithm (dynamically adjusts the water spray volume and combustion load, and the temperature fluctuation is ±2°C); its self-cleaning spiral heat exchange tube group (nano-coating + shock wave soot blowing dual-effect anti-ash deposition technology) and modular quick-installation design (single module replacement takes less than 3 hours) suppress the long-term operation heat transfer efficiency attenuation rate to less than 5%, which is suitable for biomass power generation, chemical parks and other scenarios, and provides a modular thermal solution for steam power systems with efficient recovery, precise temperature control, and long-term stability.

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

R&D and Production:

Ruiding has established the jiangsu province clean incineration resource engineering technology center and the key laboratory of the JICUI-Ruidings joint innovation center.
