Integrated afterheat hot water burner assembly

Abstract

The invention discloses an integrated afterheat hot water burner assembly, which consists of an ignition device, a burner and a hearth, wherein the burner comprises a gas inlet pipe, a gas anti-blocking partition cap, a gas pre-heating partition burning tray, an inner wind sleeve and an outer wind sleeve; the hearth is a sandwich-type hearth and comprises an inner wall, an outer wall and a gas cavity clamped between the inner wall and the outer wall; a metal water pipe is arranged in the gas cavity; the metal water pipe is spirally wound on the outer side of the inner wall; the metal water pipe tightly contacts the inner wall and the outer wall; a water inlet end of the metal water pipe is communicated with a water inlet pipe at the outer side of the hearth; the water outlet end of the metal water pipe is communicated with a water outlet pipe at the outer side of the hearth. According to the invention, not only is waste of heat effectively prevented, but also the kept heat is heated through the inner and outer wind sleeves to enter into the air inside the burner; high-temperature exhaust gas also enters into the gas cavity through a discharge hole at the upper end of the inner wall of the hearth and carries out heat exchange with water in the metal water pipe, so the heating efficiency of the burner is improved, thereby saving the energy source and improving the service life of the hearth.

Description

technical field

[0001] The invention relates to a commercial burner assembly, in particular to a commercial burner assembly used on a Chinese frying stove. Background technique

[0002] Existing commercial burner assemblies suffer from the following disadvantages. 1. Although the existing commercial burner assembly collects waste heat, it reduces the speed of cooking, that is, only partial energy-saving technology is used, and comprehensive energy-saving is not achieved. 2. Although some furnaces have adopted a water jacket to cool down, the manufacturing process of the water jacket is very troublesome, and when in use, the heat exchange area between the high-temperature exhaust gas generated by the burner and the water jacket is small, and the high-temperature exhaust gas generated by the burner is often only It will heat the top of the water jacket locally, which causes the problem of local high temperature in the water jacket (the water in the water jacket is easy to boi...
