The use of waste in a coal-fired boiler system. A demonstration at Leicester Royal Infirmary (GB)

Miscellaneous:

Abstract

A demonstration at Leicester Royal Infirmary in the United Kingdom has shown that cost savings of almost 16,000 pounds/year could be achieved by replicators who are considering the conversion of existing coal-fired boiler equipment to firing on a mixture of waste and coal. The project involved the installation of two waste-shredding machines, a Claas Bomatic and a Mono Muncher for the handling of clinical and other combustible waste. These were linked via waste-blowing paddle fans and steel waste-transfer pipes to two GWB Vekos fixed-grate waste/coal-fired boilers. The boilers were set to burn approximately 220 kg/h of coal and an equal quantity of shredded waste. When burning coal alone, the boiler achieved a gross thermal efficiency of about 82%. When burning coal and waste, the thermal efficiency was calculated to be around 81.5%. These figures compare favourably with new conventional gas and oil-fired installations and were within the figures specified by the boiler manufacturer. In describing the experience of operating this demonstration plant, the report draws the attention of would be replicators to the need to pay attention to selecting a shredder which is sufficiently robust and is appropriate to the type of waste involved.
