Weiss ApS products

District heating  as the name indicates is a system that distributes heat, which is generated in a centralized location and used for commercial and residential needs such as space heating or water heating. The heat often is produced by plant burning fossil fuels. The growing focus on climate change is forcing a search for new sustainable solutions and in recent years biomass is becoming a new and efficient district heating fuel. District heating plants operating on biomass are highly efficient and provide excellent pollution control. Energy recovered from biomass fuels such as wood chips, straw or pellets substantially reduces CO2 emission into the atmosphere. Also incinerating biomass waste vastly helps reducing the demand for landfills. Weiss district heating plants based on biomass combustion technology are state-of-the art designed and well tested turn-key solutions fitted to clients’ highest expectations.

Process Steam production from biomass can reduce significantly energy costs. The most common way of utilizing biomass is direct combustion that results in hot flue gases producing steam in a boiler – a technology that was discovered back in XIX century. Today’s boilers are differentiated by their configuration, size, and the quality of the steam or hot water being produced. Up to 70% in fuel costs can be saved by using biomass such as: straw, wood chips, waste from crops, husk,etc. Weiss designs energy plants tailor made for customers needs and requests. Process steam can be used in many production processes like: cooking, baking, boiling, cleaning, destillation, pasteurization and others, where high temperature is required.

The movable combustion grate is used for both dry and moist fuels. For dry fuels the grate is used in case of major plant outputs or difficult fuel types such as straw, husks and grain. In these particular cases the grate will be designed with water cooling. In case of moist fuels the combustion chamber will be brick-lined. The design of the brick-lining depends on the water content of the fuel and whether an extra high temperature combustion chamber shall be included in the plant for evaporation of the water.

The control of a WEISS combustion plant has always had high-priority. For that reason we have ourselves always specified the operating parameters that our plants shall observe. At present the specifications and concepts of the control panel are determined by our own specialists, this means that programming specialists in consultation with combustion technicians are your guaranty for a quality product fulfilling the stipulated specifications. As a minimum all our plants are controlled with a view to under-pressure and 02 percentages in the flue gas. For this a frequency converter is used on the flue gas fan. Starting from the smallest industrial plant and upwards as standard all plants are fully modulating within their load area. As standard the plant is operated via the touch screen mounted in the main switchboard. Through this the operator gains access to change set-points and to watch ordinary functions with alarm lists etc.
