Lime manufacturing

In North America, quicklime was produced locally as early as 1635 in Rhode Island. It was not until 1733, when lime was shipped by boatioad from Rockland, Maine, to Boston, that lime manufacture was estabUshed as a significant iadustry in commerce. The commercial hydration of lime is a relatively recent development initiated in 1904. Technical progress has allowed the industry to advance rapidly during the latter part of the twentieth century. 

Although most lime is sold as quicklime, production of hydrated lime is also substantial. This product is made by the lime manufacturer in the form of a fluffy, dry, white powder, and its use obviates the necessity of slaking. Small lime consumers caimot economically justify the additional processing step that hydration entails.

Controlled burning of tires or TDF for fuel value occurs most frequently in tvo types of process units - kilns and boilers. This chapter will describe the general process operation of cement kilns and boilers. The various types of boiler configurations will be described with attention to the implications for burning tires or TDF. Kilns in two industries have burned tires or TDF supplementally - lime manufacturing and, more commonly, cement manufacturing. 

The portland cement production process is extremely energy intensive (from 4 to 6 million Btu s (MMBtu s) are required to make a ton of product) therefore, alternative and cost-effective fuel options are of great interest. Waste tires have been tried as a supplemental fuel in veil over 30 cement kilns and in at least one rotary lime manufacturing kiln. Currently, tires are in use, either on a trial or permanent basis, in 11 cement kilns and one lime kiln.

MKD is a by-product of lime manufacture and is collected from the chimney of lime kilns. It is a blend of calcium carbonate and calcium hydroxide. The MKD used in this project was supplied in a fomi of white powder. Its bulk density was 1000 kg/m and the grading was 95% passing through 500 pm sieve. The typical chemical analysis of the MKD used is given in Table 1 (section 2.1.3).
