JPH11182820A - Oxygen type ultra-high temperature burner and drying and melting device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To permit drying, crushing and melting, which could not be done with a simple facility through a conventional burner, promote the cleaning as well as the reduction of waste gas and contrive the reduction of volume as well as the recycling of waste, by generating ultra-high temperature and high-speed flame employing pure oxygen and kerosene. SOLUTION: A drying and melting device is constituted of a decomposing and melting tank 13 for a matter to be treated, which is connected to an oxygen type burner device through a duct or the like, a high-temperature and high-speed evaporating device, consisting of a liquid spray mixer 17 connected directly to a decomposing tank, a pump 17 for supplying a matter to be treated, and a water tank, provided below the decomposing and melting tank 13 to change molten matter into slag. Pure oxygen is employed as oxidizing agent for burning fuel while the fuel is injected under the condition of pulsating mist to generate annular explosion flame, having the high temperature of 2500 deg.C or more and a high speed, higher than two times of the speed of sound. The high-temperature and high-speed flame can treat highly efficiently the drying, crushing and melting treatment of the matter to be treated by a simple facility within a short period of time while saving energy.

2. Description of the Related Art Conventionally, the combustion structure of a burner is composed of a fuel spraying device, a combustion air blower and an ignition device. Excess air is required for complete combustion, so that the combustion flame temperature and the calorific value are limited. In addition, there is a problem that more nitrogen oxides are generated as the combustion proceeds at a higher temperature. Further, in processes such as dehydration, drying, crushing, and melting of a substance, a fuel is burned, and the thermal energy of the fuel is directly and indirectly brought into surface contact with the substance to be treated, thereby treating the latent heat of evaporation. However, in the conventional method, there is a problem that an average heat exchange cannot be performed on the object to be processed, the efficiency is extremely low, and a large amount of exhaust gas and a large amount of energy and time have to be wasted in processing. Was.
