80kW Once Through Boiler (OTB) fired by iron combusted flue gasses (<XXum) with temperatures up to 600C. Water to saturated steam generation by use of forced convection boiler principle. Dry saturated steam generation up to 150C at 3.5barg, suitable for industrial low pressure steam processes.
Used as a proof of principle annex research setup and part of the 100kW Metallot iron combustion system. The delivered subsystem consist out of a modular stacked boiler skid with a complementary process skid, equipped with a vessel, pump, pressure control valve and corresponding pressure safety equipment. The control cabinet is carried out with a data acquisition and control system and is operational via a touchscreen control panel.

Preliminary design for a test setup of a drain water thickener. Drainwater is a common residual product in a variety of thermal cleaning processes. Discharge of drainwater is cost intensive and therefore volumetric reduction (e.q. thickening) of drainwater is desired to reduce discharge costs. Heat Power B.V. has designed and fabricated a small test setup that is able to thicken the drainwater of a thermal cleaning plant, by use of the factory’s excess heat. The system makes use of a Once Through Boiler heat exchamger where saturated steam is generated from saturated water. Due to the active control system, the output steam conditions are kept constant despite the varying heat output of the plants excess heat.
This technique has the capability of reducing drain water up to 10% of the original capacity, resulting in 10 times the original discharge costs. The drainwater thickener is capable of replacing active cooling devices such as ventilators or quenches, to reduce the operational costs even further.
