Book excerpt: The wood-fired boiler at the Vermont State Hospital in Waterbury, Vermont was investigated in order to identify environmental and economic problems associated with increased use of wood as fuel. The investigators observed that the low amount of stack emissions contained particulates that were extremely effective light scatterers. An analysis of the entire system was performed in order to investigate the particulate growth and the conversion of gaseous material to particulates within the system. Initial findings indicate that a good deal of particulate formation takes place within and after the cyclone, thus rendering the cyclone somewhat ineffective in this system. Meteorological data were acquired in the vicinity of the experimental site. Background concentrations were measured using hi-vol samplers and a Tracer experiment was performed to indicate the direction of plume travel. These data were incorporated into the Los Alamos Visibility Model to simulate the actual appearance of the plume with a variety of boiler sizes. This simulation gives one an indication of how large a boiler, sited in this location, can be before the opacity of the plume becomes aesthetically offensive. An economic assessment of the wood burning activities at Waterbury and a number of other sites is included in this report.
