PH Kinzett Ltd
Consistent warmth is critical to the hydroponic tomato growing process. In common with most South Island growers, Kinzett had been fuelling its boilers with coal, burning between 1,000 and 1,200 tonnes a year. This added up to a major cost for the business, second only to its labour costs.
Additionally Kinzett wanted an environmentally friendly fuel option lower in CO2 and particulate emissions and less dirty for its staff to handle. Technical advice showed that it was practical to convert the existing coal boiler to wood.
A payback analysis suggested that the project would pay for itself in three years.
The main boiler is a Morrow Engineering ‘Tripass’ rated at 4MW converted from coal to wood chip
