Abstract: A steam generator for generating steam by boiling water, or other hot water heating device, in either case such as for use in a steam cooker or warewasher, includes a tank structure providing a heating chamber for holding water, and at least one heating element associated with the tank structure for heating water. The tank structure includes a main body wall having a U-shaped cross-sectional profile formed by opposed first and second side wall portions of the heating chamber and a curved bottom wall portion of the heating chamber, wherein the curved bottom wall portion is monolithic with the first and second side wall portions, wherein the main body wall is sheet metal material that has been curved.

Abstract: A steam generator includes a tank for holding water, and a heating system associated with the tank for heating water in the tank to produce steam, the heating system including a gaseous fuel burner that produces hot combustion gases. A steam superheater compartment receives combustion gases from the heating system and that includes a steam line therein that receives steam from the tank to provide heat exchange between hot combustion gases traveling through the compartment and steam traveling along the steam line. A tank feed water pre-heat system that receives combustion gases from the heating system and that includes a water feed line therein to provide heat exchange between hot combustion gases and water within the water feed line, wherein the water feed line is connected for delivery of pre-heated water to a water inlet of the tank.

Abstract: A cooking appliance includes a housing, a cooking area or volume on or in the housing and a heater assembly for heating the cooking area or volume. The heater assembly includes a heater plate body with a surface having at least one groove therein. The groove includes both a deformable metal sheet element and a resistive heater element therein. The deformable metal sheet element is pressed between an outer surface portion of the resistive heater element and a surface portion of the groove to provide a thermal transfer path from the resistive heating element and to the heater plate body through the deformable metal sheet element.
