Contents Notes
A digital computer program was developed for the preliminary design and cost estimation of an optimum multiple-hearth-furnace system for sewage sludge incineration. The program was primarily based on field data from nine operating plants, each having one to four furnaces. The individual furnaces covered a range in capacity from 200 to 4500 lb dry solids per hours. Operating schedules and thermal cycling were considered, and costs were normalized to 1969 dollars. The computer program provides the number, dimensions and ratings of components; expenditures of labor, fuel and power; and all the cost elements for an incineration system which is to process a given flow of sludge having specified characteristics. Cost breakdowns are calculated for capital, total cost per annum and total cost per ton dry solids incinerated. The computer program may also be used for the thermal analysis of a multiple-hearth furnace incinerator without design and cost features.
