HoSt supplies water tube steam boilers. In a water tube steam boiler water flows through the pipes and the flue gasses pass around the pipes. Water tube steam boilers are applied above 32 bar and with difficult fuels.
This type of boiler can be cleaned automatically and with ease. High pressure steam is blown, with a lance, between the pipes to remove dust. In this way the water tube bundles are cleaned thoroughly.
Difficult fuels with a lot of sodium and potassium, such as straw, chicken manure and pulp, tend to deposit a harsh stone kind of deposition on the pipes. Cleaning is therefore an important issue; and a major advantage of the water tube boiler.
For specific fuels with a very low ash melting point (and with RDF), the boiler is built in two sections. The first section is a cooled membrane section; a radiation cooler. The flue gas with fly ash is cooled in this section to prevent harsh stone-like ash deposits in the pipe bundles. The second section is made from evaporator pipes.
Advantages of HoSt boilers

Projects & more information
HoSt has already realised multiple biomass-fired combined heat and power plants in both the Netherlands and abroad. A complete overview of our projects is available here. Interested in what we can offer? Or interested in visiting one of our projects? For example the wood-fired bioenergy plant in Beetgum, the bio-CHP in Strijp or in Meerhoven? Or need more information? Contact us now.
Bio-CHP Strijp supplies heat to the district heating net of Eindhoven. The plant burns wood chips and produces green electricity as well as heat. The installation is equipped with a flame tube boiler.
