This novel approach to textbook publication is made up of a book plus a computer diskette. The book contributes to the ability of environmental engineers to solve hazardous waste incineration problems by presenting almost 100 specific problems and their solutions. It also contains a user's guide to software provided on the diskette. The diskette itself contains procedures that provide thermochemical calculations relating to waste incineration, stoichiometric calculations of incinerator emissions and incinerator design.
