Tittle:
Device for cleaning heat transfer surfaces of boilers of small and medium thermal outputs
Summary:
Czech university developed technology of cleaning mechanism for boilers of small thermal outputs. The university is looking for industrial and business partners who would be able to produce boilers of small and medium thermal outputs suitable for central heating of households and public buildings. The university offers license agreement.
Description:
The technology is designed for cleaning interior heat transfer surfaces of domestic boilers by pulsed blowing using compressed air. The device requires professional installation and regular service; however any person can operate the device easily without any qualification or having pre-training. Electricity is necessary for compressing the air and proper production of pulses in the shockwave generator.
The purpose of the invention is to enable comfortable and especially regular removal of solid deposits on heat transfer surface of boilers with low and medium heat outputs by pneumatic pulses generated in a shockwave generator. The shockwave generator is a source of pressurized gaseous medium that is through one or more nozzles directed to the heat transfer surface of the boiler. The nozzles are installed inside the boiler, while the shockwave generator is located outside the boiler. Both parts are connected by a pressure hose. Dynamic stream of gaseous medium leads to erosion of deposits on the surface; the frequency of pulses is determined by opening manual or automatic valve.
The university is looking for industrial and business partners who would be able to produce and distribute the device and offers license agreement.
Advantages and Innovations:
Keeping heat transfer surfaces of domestic boilers in relatively clean state requires active intervention by the operator, who, by mechanical means such as hand tools, removes suspended sediment. The operator is often not aware of the need for such measure, leaving the boiler without maintenance for a long time. This eventually leads to continuous deterioration of performance and emission parameters of the boiler due to the decreasing intensity of the heat transfer from the flue gas into the water heating circuit. Higher temperature of not sufficiently cooled down flue gas results in increase of heat losses and wasting of usable heat. The proposed technical solution compared to the current situation offers a convenient way to clean heat transfer surfaces without the need for direct access. This allows implementing the cleaning process in full operation of the boiler. Another advantage is the efficiency of cleaning the surface in inaccessible parts of the boiler and the possibility of regular cleaning at periodic intervals.
