Three heat recovery boilers put into operation at a cost of nearly $6 million are saving the Tenneco Chemicals plant in Pasadena, Texas substantial amounts of natural gas previously used to generate steam in the boiler house. Two of the heat recovery boilers were installed as retrofits on the exhausts of two gas turbines which drive 7500-hp gas compressors. The boilers reclaim heat previously wasted to the atmosphere reducing exhaust temperatures from 900 to 300/sup 0/F. The third unit - a waste fuels fired boiler - burns plant liquid wastes of widely varying viscosities, incinerates a nuisance low heat value gas stream, burns plant off-gas of varying heat content, and can burn No. 6 oil for supplemental heat. These three units recover over 1 trillion Btu/yr of previously wasted heat, a savings equivalent to one billion cubic ft of natural gas. (LCL)
