Title of Invention:

Four Prong (Arm) Sealed Burner

Invention Abstract A sealed four pronged (armed) burner to improve time-to-boil. The design renders itself suitable for excellent turn-down by incorporating a second burner in the design to make assembly a stacked design.

Problem or requirement addressed by the invention Increased thermal capacity of the burner does not necessarily translate into improved thermal efficiency measured in terms of time-to-boil. This design addresses that by moving some heat toward the center of the burner (and hence pot) and thereby increasing the heat flux into the pot.

How the invention works Expanding on answer to the previous question, in one embodiment of the current invention a hybrid stacked burner is disclosed wherein the top main burner draws primary air from under the cooktop and the bottom simmer burner draws air from atop the cooktop. In one of its embodiment a stacked burner provider the simmer chamber is at bottom. This design is a sealed burner that can be build either as a single stage or a dual stage (stacked) gas burner. In single stage form, it draws a mixture of primary-air and gas, ignites it and produces a flame atop a cooktop for cooking. In its stacked burner form, there are two burners and a dual stage gas valve --- one of the four pronged design and the smaller burner of conventional circular design. The smaller burner is the simmer burner that can turn down from a high (say 2000 Btu/hr) to a low (say 600 Btu/hr). This burner is the first to come on and stays on as long as there is a demand for heat. The main burner comes on by further turn of the knob the main gas valve opens and flame is carried over from the simmer burner to the main burner. This burner, in this case would go for example from 2100 Btu/hr to say 18,000 Btu/hr.
