Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the swirl burner is designed as a whole, including three parts: swirl generator, combustion section and heat exchange section. Gas pipes and air pipes are designed on the swirl burner. Its volute structure is a whole steel plate rolled and welded, and the gas pipe, air pipe and generator are connected by welding as a whole. On the gas and air pipes, pipe threads are reserved to facilitate the connection with the corresponding pipes during on-site construction.

[0017] At the outlet of the swirl generator, a combustion section is installed, and the connection between the two is connected by welding. The specific connection method is: the whole steel plate of the combustion section is coiled and welded into a cone structure with an inclination angle of 10-30°, and the outlet of the swirl generator is welded to the steel plate on the ...

Abstract

A cylindrical radiation porous medium heater capable of achieving diffusive combustion in a cavity comprises a gas pipe, an air pipe, a rotational flow generator, the cavity, an electronic ignition device, first foam ceramics, second foam ceramics and third foam ceramics. Gas and air are electronically ignited after passing through the rotational flow generator, and the gas achieves rotational flow diffusive combustion in the conical cavity. The first foam ceramics are arranged around the cavity, thermal reflux is achieved through radiation heat transfer, the gas is preheated, and then flue gas enters in an airflow distribution area. The flue gas passes through the second foam ceramics and the third foam ceramics, part of heat of the flue gas is accumulated in the foam ceramics, and then the flue gas flows to a heating space. Due to the good radiation heat transfer performance of porous media, surrounding objects are quickly heated. Compared with a free flame burner, the radiation heat transfer performance can be greatly improved, heat transfer is more even, the concentration of fuel can be lower, and low heating value gas such as coal-mine gas and chemical waste gas can be combusted.

Description

technical field [0001] The invention relates to a columnar radiation porous medium heater which combines diffusion combustion and porous medium heat transfer in a cavity, and belongs to the fields of combustion technology, utilization of low-grade energy, and enhanced heat transfer. Background technique [0002] At present, my country is in the process of rapid economic development and continuous advancement of industrialization. However, the environment is seriously polluted and the ecosystem is deteriorating. It is imperative to develop efficient, economical and environmentally friendly energy utilization technologies. In order to change the status quo of energy utilization in my country, optimize the structure of energy utilization, and alleviate the pressure of environmental protection, the state vigorously advocates the development of low calorific value gas combustion technology. Porous media combustion technology, as one of the feasible combustion methods, can solve t...
