ABSTRACT

This article presents the results, obtained from testing an equipment used to obtain biogas and biochar from biomass, developed and manufactured based on a patent developed on a research and development project by the IHP staff. A modern way in order to produce ecological and cheap thermal energy is to utilize biomass through micro-gasification process called TLUD (Top-Lit UpDraft) with high conversion efficiencies and emissions of CO and low PM2,5.
A new way for producing energy from biomass is the CHAB concept (Combined Heat and Biochar) which produces both heat and biochar (BC) with negative balance of CO2. The CHAB concept applies in those agricultural sectors which are large consumers of heat: greenhouses, drying, technological spaces. For heating greenhouses was designed and produced a hot air generator which consists from two major subsystems: the generator with gas-producing TLUD and air heater with heat exchanger flue gas/hot air.
Acceptability for long-term use of gasification technology and the CHAB and the penetration on the market depend on its economic, ecologic and technical performances of the gasification and production of biochar installations, efficiency and safety of installations that use the produced gas as well as the tolerances for the characteristics of gasification biomass.
Tests of the equipment shows the characteristics obtained from the proposed version and done by the research staff so that the operational system had to be safe, reliable, meet the environmental standards and to be economically viable. This tests whore conducted based on a methodology presented during this paper.
