| Mushroom Processor - Boiler Recuperator |
| Faced with increasing energy costs this major mushroom processor initiated an energy audit. Rising fuel costs quickly focused attention on the three process boilers used to supply steam for the facility. Three Superconducting Gas to Water H/E (GW) units were selected to recover waste exhaust heat and pre-heat the boiler return feed circuit. Each of the boilers presented its own challenges in terms of flue alignments for the retrofit of the GW units so custom instead of standard models were used. The net effect was a 25% reduction in overall boiler running costs and a 15-month return on investment. The units operate virtually maintenance free and can be easily accessed for inspection and basic cleaning during the normal boiler maintenance schedules. |
