HoSt products

HoSt has a broad experience in supplying industrial biogas plants. In these industrial biogas plants, organic waste currents are digested without the addition of manure. We have supplied systems for processing slaughterhouse waste, industrial and municipal primary and secondary sludge, unpacked food products, and industrial food products.

HoSt supplies cylindrical flame tube boilers. In this type of boiler the shell is filled with water and the flue gasses flow through the flame tubes. For improved cleaning, the first part of the boiler is equipped with a radiation section where the flue gasses are being cooled before they flow though the flame tubes. The cooling in the radiation section prevents harsh and hard to remove ash depositions in the flame tubes. In addition, for regular cleaning the cylindrical boilers can be equipped with compressed air soot blowers to minimise the number of production stops.

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.

HoSt acts as a turnkey supplier of (air blown) fluidized bed gasifier plants. By means of gasification biomass fuels can be converted to a combustible syngas, which can be cleaned and used in several kinds of power generation equipment. Gasification is a feasible technology for thermal conversion of waste, meeting the strict emission limits.
