Pre-mixing type heat exchange commercial energy-saving and environment-friendly gas stove

Abstract

The invention discloses a pre-mixing type heat exchange commercial energy-saving and environment-friendly gas stove. The stove mainly comprises a combustion device and a heat exchange device; the combustion device comprises a cylinder gas-air mixing bin, an energy-saving stove head, a throttling air valve and a throttling gas valve, and the combustion device further comprises a refractory materiallayer refering to a furnace wall surface in contact with a burner head; and the heat exchange device is a circular conical column body internally with two hollow interlayers, the structure of the heat exchange device is large in upper part and small in lower part, the heat exchange device is arranged at the interior of a furnace and is divided into three layers sequentially arranged from inside to outside, wherein the innermost layer is a heat preservation layer, the second layer (the middle layer) is a conical column body hollow layer and used for waste gas emission, and the third layer (theoutermost layer) is a fresh air layer. The stove has the beneficial effects that 1, the combustion efficiency is improved; 2, the energy-saving efficiency is improved; 3, the emission of pollutants is reduced; 4, the noise is greatly reduced; and 5, the maintenance rate is reduced, and the economic benefits are greatly improved.

Description
