Abstract: A high efficiency laminar flow burner system for proving a stream of heat energy including a supply input module for providing fuel and laminar streams of air to a combustion manifold. The laminar air delivery system includes a damper, a blower, and an air delivery controller. The air delivery controller receives an efficiency signal to control the flow of a laminar air intake stream by adjusting the damper.

Abstract: To provide a combustion apparatus that has a vaporizer capable of vaporizing liquid fuel completely without complicating the structure of the combustion apparatus. The combustion apparatus has an evaporating part for heating and vaporizing the liquid fuel into combustion gas, and a premixed gas spout part for spouting out premixed gas in which the combustion gas is mixed with primary air, with an inflow port of the premixed gas spout part being provided at a position higher than the evaporating part. By configuring the combustion apparatus like this, a space for accumulating unvaporized liquid fuel is formed between the evaporating part and the inflow port, and sufficient time to completely vaporize the liquid fuel can be afforded. Therefore, unevaporated fuel in a liquid state can be prevented from flowing into the premixed gas spout part.
