Heat recovery steam boiler

The heat recovery steam boiler HRSB from Bosch Industriekessel is the ideal addition to energy concepts involving combined heat and power generation. It provides an efficient way of using accumulated flue gas heat by converting it into process steam. The type series generates, depending on the version, between 400 and 4,100 kg of steam per hour.

The heat recovery boiler, which is certified in accordance with the Pressure Equipment Directive, consists of a highly efficient tubular heat exchanger – whose efficiency it is possible to boost even further thanks to the option of integrating an economiser. In addition, the boiler is insulated with effective heat-insulating materials and features state-of-the-art safety equipment. Meanwhile, the tried-and-tested, PLC-based BCO boiler control makes operation exceptionally straightforward and convenient.

Used in conjunction with a combined heat and power unit, the heat recovery boiler can play a significant part in strategies for using primary energy efficiently. The hot flows of flue gas from the upstream combustion processes are conducted via the tubular heat exchanger and used for steam generation purposes. This additional option for using heat means that combined heat and power units can generally be designed on a larger scale than thermal heat-driven plants. The result is that the plant operator is able to obtain more of its own electricity, which in turn leads to excellent savings on energy costs and short payback periods.

The heat recovery boiler can be combined with combined heat and power units in the electrical power range from approximately 0.5 to 4 MW. Thanks to its modular design and compact dimensions, it is the ideal choice for both new plants and modernisation projects alike.

By launching the heat recovery steam boiler HRSB, Bosch is expanding its already extensive product range to offer more options in the area of efficient process heat, hot water and electricity generation. Perfectly harmonised system solutions from a single source significantly simplify the planning and installation of the energy systems. Additionally, a wide range of services such as customised maintenance packages are available to ensure the system will keep running efficiently for years to come.
