Steam boilers

Company AESI AG offers you individual solutions for the efficient steam generation based on the products of the firm Bosch: steam boilers at the power range from 175 to 55 000 kg /h.

 

 Combined heat and power with 4-pass boiler system technology 

панThe system

The  use of combined heat and power systems in the commercial or industrial sectors can provide a viable alternative. A gas turbine or a combined heat and power plant generates the electrical power – a downstream waste heat boiler system uses the hot flue gases from the upstream combustion processes for  the efficient generation of thermal energy or process heat.

Customer benefit

The  hot water or  steam generators with waste heat recovery are conventionally fired 3-pass boilers with an  additional integrated fourth smoke tube pass. The  hot flue gases from the upstream processes are passed through this to support the generation of steam or  hot water. Additional peak load boilers, which are necessary with pure waste heat boilers, can usually be dispensed with due to the self-firing. Investment costs, space requirement and expenditure on  equipment are reduced enormously.
