A burner system for a furnace. The system may have a wedged or other shaped burner box. An air-fuel mixer may be attached to a smaller end of the burner box at virtually any angle relative to a direction of a gas and air mixture leaving the larger box end. A burner head may be attached to the larger end of the box. The burner head may be sufficient for numerous heater sections of a heat exchanger. A spacer and a radiation shield may be situated between the burner head and heat exchanger. An addition of the radiation shield may reduce the operating temperature of the burner box, burner head and/or spacer. A fan may move the gas and air mixture from the mixer, through the box and the burner head. The mixture may be ignited into a flame which is moved into the heat exchanger.

A reaction chamber for a feedstock reactor includes an outer shell defining a reaction volume and having a heat-resistant refractory, an inlet for allowing a feedstock to enter the reaction volume, an outlet for allowing reaction products, formed as a result of decomposition of the feedstock in the reaction volume, to exit the reaction volume, and a protective liner lining an interior surface of the outer shell and comprising a compliant shock-absorbing layer.

A compact thermal oxidizer is disclosed, comprising a combustion chamber and a series of ducts including a first duct, a second duct, a third duct, and a fourth duct. The combustion chamber is connected to the first duct, which in turn directs fluid flow into the second duct in an antiparallel direction to the combustion chamber. The second duct is linked to the third duct, which guides the fluid flow into the fourth duct, in aa direction antiparallel to the flow in the second duct and parallel to the flow in the combustion chamber. A refractory lining is disposed on the interior surfaces of the combustion chamber, first duct, and second duct.

The invention relates to a refractory ceramic batch for the production of an unformed refractory ceramic batch, the use of a batch of this kind for lining metallurgical melting vessels and also a metallurgical melting vessel which is lined with an unformed refractory ceramic product based on a batch of this kind.

The present disclosure is directed to a burner assembly for generating a heat source. The burner assembly may include a combustion plate having a first surface and a second surface. The combustion plate may include a first plurality of holes extending from the first surface to the second surface arranged in a first circle and a second plurality of holes extending from the first surface to the second surface arranged in a second circle. The first circle and second circle may be arranged in concentric circles. The burner assembly may further be configured to have at least one of the holes having a longitudinal axis extending at a first acute angle from a plane of the combustion plate. The burner assembly may further be configured to have at least one of the holes having the longitudinal axis extending at a second acute angle from a tangent line of one of the concentric circles on the plane of the combustion plate.
