Abstract:
1. A burner plate comprising: a parallelepiped formed from a mesh material having a plurality of small holes through which air and a gaseous fuel can flow, a plurality of the plurality of small holes being substantially the same size, a plurality of the substantially same-sized small holes having substantially the same shape (holes), the parallelepiped having first and second major faces which are spaced apart from and oppose each other, the parallelepiped also having four sides having a plurality of said holes, the sides being substantially orthogonal to the opposing major faces, the sides having height dimensions substantially equal to each other and which determine a separation distance between the first and second major faces, first and second ones of the four sides being opposite each other and having lengths substantially equal to each other, third and fourth ones of the four sides being opposite each other and substantially orthogonal to the first and second sides and having lengths substantially equal to each other, the parallelepiped having a width defined by lengths of the first and second sides, a length defined by lengths of the third and fourth sides and a height defined by the distance between the first and second opposing major faces, the holes in the faces and sides being substantially evenly spaced-apart from each other across the first and second major faces and evenly spaced apart from each other across the sides; the parallelepiped being formed from first and second separate portions, which when joined together form the parallelepiped and an air/fuel mixture space defined by an open space between the first and second mesh major faces and the space enclosed by the four sides; wherein the parallelepiped and the holes are sized, shaped and arranged such that air and a gaseous fuel passing through holes in the first major face, become turbulent in the mixture space, mix together in the mixture space, pass through the holes in the second major face and whereat the gaseous fuel burns adjacent the second major face such that the second major face is heated to emit infrared energy, the size of the small holes in the mesh material being selected to prevent ignition and combustion of the air/fuel mixture in the mixture space.
