3 1. COMPANY INTRODUCTION

4 Poppi Clementino S.p.A. is an italian company that operates in the fields of purification and energy recovery since Company Mission: Plants easy to realize and to manage. Continuous development and research to improve purification system, savings and energy efficiency. Utilization of the thermal energy in excess in order to reduce fuel consumption with consequent savings in the production costs and remarkable reduced air pollution.

5 Energy Recovery Systems engineered on the following concepts: Production Parameters > mantained totally unchanged. The energy transfer from the source (boilers, kilns, etc.) to other thermal machineries (driers, spray driers) is engineered without modify the production feautures of either the source (firing curve, etc.) and receiving equipment (contamination, working conditions). Automatic Control & Constant Recovery. The systems by Poppi Clementino are equipped with centralized automatic controls.

6 MAIN FIELDS OF APPLICATION - Ceramics Tiles Industry. - Ceramic Frits and Glaze Inustry. - Glass Industry. - Plastics Industry. - Metal Foundry Industry. The List of References is available upon request.

7 2. INTRODUCTION > HEAT RECOVERY SYSTEMS

8 Recovery Methods The source for Energy Recovery is is given by the kilns, from both the Smoke Chimney and the Cooling Air Exhaustion Chimenys. The recovery flow, can be channelled to the Spray Dryers and to the Dryers, in the Dry Milling process, by two main methods: Direct Recovery Indirect Recovery [by Heat Exchangers]

9 Direct v.s. Indirect Recovery (main differences) Direct Recovery the hot air from the Cooling Zone of the Kilns is properly transferred, thanks to the proper engineering of a set of valves, pipes, pipelines, and control instruments to the users (Spray Driers, Driers). Indirect Recovery is applied in the recovery of the smoke side, because the fumes have a load of pollutants, that contains aggressive chemical agents. In this case, the recovery is made thanks to a Heat Exchanger enginereed by Poppi Clementino Spa; it is equipped with an automatic cleaning systemand its operation avoids corrosive condensations and occlusion either on the air side or in the smoke side.

10 LIST OF FACTORS THAT DETERMINE THE SAVING Recovery of large volumes of air at the highest possible temperature. Optimal insulation to avoid any leackage along the pipeline. and avoid any «thermic bridges». Automation of the recovery system in order to guarantee a constant result in terms of saving.
