Project Title: Demonstration of an Environmentally Friendly Paper Artifacts Furnace for Traditional Funeral Service and Data Analysis of Particulate Removal Efficiency of the Furnace

Applicant: Mr. Arthur LO of Tung Wah Group of Hospitals

Total Approved Grant: $2,000,000

Duration: 1/3/2011 to 30/11/2013

Project Status/Remarks: Completed

Scope:
The project aims to demonstrate the practicality of a new paper artifacts furnace design which entails minimal modification to traditional operation practices with maximum considerations to air quality of surroundings, improve air emissions and mist elimination.

Summary of the Findings/Outcomes:
A paper artifacts furnace with air pollution control equipment was built on the rooftop of International Funeral Parlour, 8 Cheong Hang Road, Hung Hom, Kowloon of the Tung Wah Group of Hospitals for demonstration of possible environmentally friendly paper artifacts burning in traditional funeral services. With proper design, equipment selection, operation and maintenance, it is demonstrated that the combined use of scrubber and electrostatic precipitator (EP) could produce no visible smoke emission in paper artifacts burning. The previous occurrence of back-firing in traditional artifacts burning is also seen to be eliminated with a sufficiently large furnace and suction gas extraction into the furnace. The flue gas temperature entering the EP is seen to have an important role in limiting the smoke emissions and should warrant further research in establishing quantitatively the relationship between overall system particulate removal efficiency and EP inlet flue gas temperature. Prospects exist in reducing water and energy consumptions of the system with further additional efforts.
