The use of coal and wood as alternative energy feedstocks is gaining rapid interests among various industrial sectors. A number of conversion technologies are either commercially available or under various stages of development to convert coal and wood to gas, liquid or solid fuels. Among these conversion technologies, the gasification of coal and wood to produce low-Btu gas for use as a retrofit fuel to oil and natural gas fired boilers, furnaces, and kilns, is one of the most promising near-term technologies. This paper presents technical and economic comparison of gasification of coal vs wood to produce low-Btu gas. A baseline plant capacity of 6 x 10/sup 9/ Btu/day was selected to perform conceptual design and economics for producing hot raw gas from wood; cold, clean gas from wood; hot raw gas from low sulfur coal; cold, clean gas from low sulfur coal; and cold, clean desulfurized gas from high sulfur coal. The economics of these five cases were compared to make relative assessment of the costs of producing low-Btu gas. Gas cost sensitivity curves are also developed for varying wood and coal costs.
