Heat recovery systems for solid fuels

To generate energy from solid fuels two main components are always necessary. First of all, the firing plant to burn solid fuels to generate hot exhaust gasses. The second component is the heat transfer system to recuperate the thermal energy from the hot exhaust gases and to transport it to the heat consumers.

When burning fuel oil or gas, controlling the combustion process is straight forward in controls of the combustion air supply. This ensures a complete and clean combustion without the help of additional equipment. The flue gas is clean and therefore the heating surfaces will remain free from deposits and the demands on the heater are relatively low.

Power generation systems suited for solid renewable biomass fuels require much more efforts. These fuels are often very wet. Depending on their origin, the characteristics may vary and they often contain sand or soil. This is why modern biomass firing plants are very complex and require sophisticated controls and adequate refractory lining, acting as heat buffer, in order to ensure a complete combustion. Ashes and contaminations require the installation of filters in order to prevent pollution of the environment.

Complex combustion systems, and the the danger of deposits and ashes on the heating surfaces, increase the demands on the heat transfer system considerably. This is why heat recovery systems for modern, sustainable, biomass firing systems must have excellent qualities. The state-of-the-art maxxtec 2-pass exhaust gas heaters were designed and developed to meet these demands and offer decisive advantages. To guarantee a trouble-free operation without interruptions they are equipped with the highly efficient and economic heat surface cleaning system Airmaxx4. 

Biomass fired decentralized CHP plants usually have only a small operating staff. Therefore the demands on the equipment within these sites are very high. Since 1997 maxxtec is involved in electric power generation from solid biomass. Since 2001 maxxtec  is the market leader in the supply of heat recovery systems for decentralized biomass fired CHP plants with ORC-package. Continuous development enables us to deliver products which meet perfectly all demands of the operators. Safe operation and outstanding efficiencies of your plants are guaranteed, because we can supply you, a high number of specially developed products, such as the Pumpmaxx pump monitoring system, which no other supplier can offer.
