An experiment was conducted in nine 200-m2 earthen ponds at the Asian Institute of Technology (AIT), Thailand from 17 July 2003 to 3 March 2004 (230 days). The objectives of the study were to assess the feasibility of co-culture of lotus and hybrid catfish in intensively fed ponds, to assess nutrient recovery from feed waste by lotus plants, to assess pond mud characteristics after lotus-fish c...

Pulverized coal and biomass co-firing in the 150MWe unit of Tuncbilek power plant is computationally investigated, within scope a preliminary feasibility study. The considered furnace, burning Turkish lignite, has totally eighteen burners, positioned at three different levels. First, pulverized combustion furnace calculated predicted temperatures boiler first pass are compared with previous mea...

Plant biomass allocation between below- and above-ground parts can actively adapt to the ambient growth conditions and is a key parameter for estimating terrestrial ecosystem carbon (C) stocks. To investigate how climatic variations affect patterns of plant biomass allocation, we sampled 548 plants belonging to four dominant genera (Stipa spp., Cleistogenes spp., Agropyron spp., and Leymus spp....

Torrefaction of biomass pellets is considered as a useful pretreatment technology in order to convert them into a high quality solid biofuel that is more suitable for pyrolysis, gasification, combustion, and co-firing applications. In the course of torrefaction, the temperature varies across the pellet, and therefore chemical reactions proceed unevenly within the pellet. However, the uniformity...

In this paper, the annual and economic performance of an integrated solar combined cycle (ISCC) with indirect energy storage tanks is investigated. The study includes four scenarios, in which the combined cycle performance was studied exclusively in the first scenario. In the second scenario, the integrated solar combined cycle (ISCC) was examined, and the use of supplementary firing instead of...

Abstract As China ramped-up coal power capacities rapidly while CO 2 emissions need to decline, these would turn into stranded assets. To deal with this risk, a promising option is retrofit co-fire biomass and eventually upgrade CCS operation (BECCS), but the feasibility debated respect negative impacts on broader sustainability issues. Here we present data-rich spatially explicit approach esti...

Biomass is a renewable energy source with great potential worldwide and in the European Union. However, valorization necessary to turn many types of waste biomass into tradable commodity that has replace coal power plants without significant modifications firing systems. Mild pyrolysis, also known as torrefaction, thermal process low-quality could be suitable for such purpose. In this work, typ...
