Description

Composite durable energy-saving commercial stove hearth

Technical Field

The utility model relates to the field of stove hearth correlation, in particular to a composite durable energy-saving commercial stove hearth.

Background

The hearth is a three-dimensional space surrounded by furnace walls for fuel combustion. The hearth has the function of ensuring that the fuel is burnt out as much as possible, and cooling the temperature of the flue gas at the outlet of the hearth to the temperature allowed by safe operation of the convection heating surface. For this purpose, the furnace should have a sufficient volume and be able to arrange a sufficient amount of heating surfaces. In addition, the hearth has reasonable shape and size so as to be matched with a burner, and organizes an air force field in the hearth, so that flames are not adhered to walls, are not punched, have high fullness, have uniform wall heat load, and are mostly used in cooking benches such as commercial big cookers, commercial frying cookers and the like.

The existing gas stove hearth is provided with three types of pond sludge hearth refractory bricks and a metal hearth, wherein the pond sludge hearth is formed by a refractory cement perlite refractory mud refractory sand mixed structure, is easy to crack under high-temperature continuous firing, and has weaker overall heat exchange; the metal hearth has better cracking resistance, but common cast iron and stainless steel materials have low heat emissivity and poor heat exchange effect.
