Problems solved by technology

[0003] The present invention aims at the problem that the outlet flame temperature of the combustion device in the existing fuel oil and gas heater is high, which causes ablation of the heat exchange device and excessive loss of heat energy. The degree of ablation of the heat exchange device of the gas heater improves the performance of the fuel and gas heaters. The invention also provides a fuel and gas heater using the high-temperature flame splitter

Embodiment Construction

[0021] The present invention will be described below in conjunction with the accompanying drawings.

[0022] figure 1 It is the structural representation of the high-temperature flame flame distributor of the present invention, figure 2 for figure 1 A view from direction A. The high-temperature flame distributor includes a guide body 1 and two support plates 2 welded together with the guide body 1 for fixed support. The support plates 2 are symmetrically arranged on both sides of the guide body 1 and along the direction of the central axis of the guide body 1. It is provided that the guide body 1 is a through hollow frustum with a certain taper made of heat-resistant steel plate 1Cr25Ni20Si2 with a thickness of 3 mm to 5 mm or other heat-resistant metals. A special high-temperature heat-resistant ceramic coating can be evenly sprayed on the surface of the diversion body 1. The high-temperature heat-resistant ceramic coating is a ceramic sprayed by flame nozzles of aerospac...

Abstract

The invention relates to a high temperature flame divider and a fuel and gas heater. The high temperature flame divider is used for reflecting high temperature flame from a burning device in the fuel and gas heater to a heat exchanger and comprises a diffuser and a supporting structure fixed on the side face of the diffuser, wherein the supporting structure is arranged along the direction of a central axis of the diffuser; the diffuser is a through hollow frustum with a certain conicity. The high temperature flame divider has the advantages of reducing the burning extent of the heat exchanger of the fuel and gas heater caused by a high temperature flame, increasing the radiation heat exchanging area of the high temperature flame, decreasing the heat energy loss and the tail gas pollution extent while improving the heat exchanging efficiency of the fuel and gas heater.

Description

technical field [0001] The invention relates to a high-temperature flame diversion flame separation technology, in particular to a high-temperature flame flame distributor used in the combustion process of fuel oil and gas heaters, and fuel and gas heaters using the high-temperature flame flame distributor. Background technique [0002] Oil and gas heaters include a combustion device and a heat exchange device. The heat released by the full combustion of fuel oil or gas in the combustion device enters the heat exchange device for heat exchange. Due to the increasingly perfect combustion technology, the volumetric heat intensity of the combustion device in the oil and gas heater has been greatly improved. The high-temperature flame temperature at the outlet of the combustion device can reach 1200 ℃ ~ 1800 ℃, and the high-temperature flame directly hits the wall of the heat exchange device. It is easy to cause ablation of the heat exchange device and excessive exhaust gas disc...
