Abstract
An ice resurfacing sled including a fuel source directing fuel to a manifold which distributes it under a regulated pressure to a plurality of orifices where it is burned in expansion chambers. The hot gas flows into a melting chamber formed by a top surface, two lateral sled runners and the surface of the ice to be melted. The melting chamber is shaped to have a reduced cross sectional area near its rear outlet to assist in maintaining the flow of heated gas beneath the sled to optimize melting. A wind screen is provided at the rear of the sled to prevent tail winds from disrupting the flow of hot gas through the melting chamber.
