Energy recovery

Thermal treatment of waste recovers energy that ca be usefully employed to generate electricity, heat for district heating purposes or process steam, in almost any number of combinations. The first step is to generate steam in a steam boiler.

 

Combustion and energy utilization (i.e. the combustion system and the steam boiler) go hand in hand and must be appropriately matched. As early as 1964, MARTIN directly integrated the steam boiler into the combustion system in the plants in Rotterdam and Paris-Issy les Moulineaux. This concept was further developed and is used for different boiler types on a world-wide basis.

 

Selection of the appropriate boiler type and its dimensioning is one of our key services, based on our many years of experience. We determine arrangement, size and dimensions of the heating surfaces, i.e. of radiation passes, superheater, evaporator and economizer. Furthermore, we specify the type and quality of the ceramic lining in addition to the detailed engineering at the interfaces. Our scope of supply includes recommendations regarding the arrangement and type of online cleaning devices for the heating surfaces as well as for measurement and control systems. High availability and long service periods can thus be achieved.

 

In times of growing concern relating to climate change and a shortage of / rise in costs of primary sources of energy, efficient utilization of energy derived from waste has become more significant. Particularly in Scandinavia, combined useage of power and heat has been in operation for a long time. A higher efficiency for electricity generation can be reached when combining a waste-to-energy plant with one utilizing fossil fuels. MARTIN's experience and references also cover all these fields.

 

Manufacturing of the steam boiler is done in close contact and cooperation with carefully selected specialist companies. MARTIN can either subcontract 'packages' or tender and order individual components. In all cases, our design is the basis.

 

Various boiler designs are shown below by way of examples.
