Compact Two-Stage waste Gasification for small-scale CHP production

During the Compact 2G project, Energos Contract (formerly called RSM Contract) in collaboration with SINTEF ER has developed a novel compact reactor for gasification of a variety of non-recyclable waste fractions for small-scale heat and power production. This project has realized several specific innovations related to the design of gasification reactor technology: i) the grate and the gasification chamber are designed as one integrated modular component, separate from the pyrolysis and combustion chamber, which can be easily dismounted for maintenance. This design has a low capital cost and also enhances the recovery of heat from the gasification product gas to the fuel bed; ii) the ceramic radiation plate is design as a simple low-cost prefabricated plate that can be easily inserted in the pyrolysis chamber through refractory guides. This allows facilitates the maintenance of this plate; iii) preheating of the gasification air can be achieved effectively through a simple double pipe. Therefore, the reactor design developed during the project can potentially reduce capital and operating costs while producing a high quality syngas which can be utilized in IC engines for high-efficiency electricity production. Energos Contract can realize the achieved design innovations to further develop the acquired Energos? waste gasification technology and gain competitiveness in the current national and international market for CHP production from waste streams. Also, the results from the project provides to Energos Contract added value related to ownership of new intellectual property and knowhow

The underlying idea of this project is to develop and prove a new compact reactor for gasification of waste for small-scale heat and power production. The proposed gasification concept aims at reducing capital and operating costs in heat production while producing a high quality syngas which can be utilized in IC engines for high-efficiency electricity production. The specific innovations are: i) to use ceramic porous materials to enhance heating of a fuel bed during drying and pyrolysis keeping the transfer of dust to the gas-phase low and ii) separate and enhanced char gasification for production of syngas with high calorific value and low tars content. Based on the applicant's search in the literature and the patents database , the specific innovations proposed in this project do not exist in the market and has not been patented. The realization of the proposed innovation will provide access and competitiveness for the applicant in the current national and international market for CHP production from waste streams. Also, a successful outcome of the project will give RSM ownership of a new technology with additional added value in terms of intellectual property and commercial licensing. The proposed innovation is relevant for meeting main political targets in the energy sector in Norway and Europe through i) increase competitiveness of the Norwegian industry, ii) increase utilization of the renewable energy resources, and iii) increase efficiency and flexibility in energy production.
