摘要

There exists a considerable problem with poultry producers in that they have been in the habit of storing and disposing of animal waste on the ground, often spread as a fertilizer, from which the waste has seeped into the local watershed. In Maryland, where a lot of poultry producers operate, the problem has become so pervasive that the waste has contaminated some areas of the Chesapeake Bay and has actually killed fish because the nitrogen in the waste promotes growth of algae, robbing the water of oxygen. This is an intolerable situation, apart from the unpleasant odors that such animal wastes cause, with the inevitable offense to the local population. This program of development has centered on the use of an Internally Circulating Fluid Bed (ICFB) boiler which will burn waste fuels, including poultry litter. This boiler can be made in the range of 3,000-50,000 lbs/hr, but the company has designed complete modular small co-generating power plants in the range of 50 ― 200 KWs electrical generation with equivalent steam outputs of 3,000 ― 12,500 lbs/hr of steam. These plants would fit on a particular processors or grower's premises and supply electricity and steam for heating the chicken houses by burning the poultry litter. The company has an ICFB already installed at a nursing home near Pottsville, PA, which has been tested on poor grade anthracite and bituminous coals. Tests on poultry litter have been carried out by the Energy Institute of Penn State University under identical combustion conditions to the full size boilers and full emission testing was carried out. The results of these tests are reported in this paper. The complete design of the modular plants of the sizes 50, 100, 150 and 200 KWs has been completed. The capital and running costs of these plants have been computed and talks with the processor for the siting of the first one is under way. The detail costs involved in building the plant are reported in the paper.
