The present invention relates to a heating combustion method.

換がなされて−る。2- Conventionally, heat treatment has been performed using fuels such as B and O heavy oils in industrial heating furnaces such as steel heating furnaces, heat treatment furnaces, and melting furnaces, but in recent years, there has been a need to prevent air pollution, etc. Due to stricter regulations on
Fuels are being converted to light oil fuels such as naphtha, and further to gas fuels.

現象が生ずる。However, as a result of this conversion to silica and gasification of fuel, RCM oil and gas fuel have been changed to have the same calories in heating furnaces, heat treatment furnaces, melting furnaces, etc. that used to use heavy oil as fuel. When used, unlike in the case of heavy oil, phenomena that can be thought of as energy loss occur, such as the atmospheric temperature in the furnace being 101 sS degrees lower and the rate of temperature rise of the object to be heated becoming slower.
本発明者等の研究に工れd%これらの現象紘次の1うな
原因によるものであると推定される。Based on the research conducted by the present inventors, it is estimated that these phenomena are due to one of the following causes.

著しく減少し、輻射熱の放射が少々くなった為、熱効率
の低下、エネルギーロスが生じたものと考えられる。In general, the heat transfer to the surface of the heated object in the furnace is by convection (6) heat transfer by radiation, 41Kml.
Of the radiation transfer, the light emitted in the furnace by fine carbon grains, which are the decomposed components of the fuel, is the so-called radiant radiation, which accounts for a relatively large proportion. It is thought that the flame was significantly reduced and the radiation of radiant heat was slightly reduced, resulting in a decrease in thermal efficiency and energy loss.

めるのであるが、軽質油、ガス燃料を使用した場合には
重質油に比べて炉内雰囲気中に飛散しているカーボン質
が減少するため、それだけ熱効果が低下するのである。In other words, the heavy oil fuel that has been used in the past has a high carbon content and has high molecular weight carbon chains], and has a larger Φ ratio than light oil, so it is decomposed and produced in the furnace. There are also many carbon particles, which generates a lot of sparkle and increases the thermal effect, but when light oil or gas fuel is used, it scatters in the furnace atmosphere more than heavy oil. As the carbon content decreases, the thermal effect decreases accordingly.

せることかできることを見出したものである。Based on the above findings, this invention was developed as a result of intensive research to prevent a decrease in thermal efficiency during combustion of light oil fuel or gas fuel, and as a result, tungsten or its compound is dispersed in the fuel and combusted and scattered in the furnace atmosphere together with the fuel. In particular, it has been discovered that the fuel can be sprayed into the furnace atmosphere by spraying it or using a nozzle separate from the fuel.

Alternatively, the above aqueous solution may be prepared in advance as a VO emulsion and then added to the fuel or emulsified fuel for combustion.
