DRS boiler is high-tech, energy-saving and environmentally friendly independentlydeveloped by our company that integrates electromechanical, combustion and heatexchange. The boiler adopts a modular design. The body is composed of tight spiracoils and is combined with enhanced heat transfer modules to form a three-pass fluegas structural solution. Mosquito-coil-shaped coils are installed at the front and rearof the furnace, and transition coils are installed at the gaps in the inner coils. Theentire furnace is completely covered by oil pipes. The application of enhanced heattransfer modules gives the boiler a sufficient heating area, combined with an efficientfully oil-cooled fireplace, to ensure that the boiler’s thermal efficiency andenvironmentally friendly emissions meet regulatory requirements.
