Due to the high volume calorific value, boron becomes the preferred high-energy component additives. In order to do more accurate measurements, the oxygen bomb calorimeter can be used. The SQ-2 can be used as a combustion accelerant. The quality, shape, and the oxygen bomb pressure on the boron powder can be studied. The test finds the gas temperature is the key parameters that affect the combustion efficiency of boron powder. Increasing the limit temperature is an effective means to improve the measurement of heat of combustion for boron powder.

 

Heat of combustion represents its chemical potential. Because of the heating value, the most promising high-energy fuels, metal additive value people of high calorific value of boron. Ten quality 58.81MJ/kg value, heating value of sales 137.94KJ/cm3. The air at the surface boron oxide V2O3 particles is created. Partial oxidation of boron powder chemical potential (calorific value) decreases. Thus, the heat of combustion is necessary before using boron powders were measured.

 

Compared to the other metal powder, burning of boron powder are very difficult. Thus, the main problem is how hard boron powder and incomplete combustion, heat of combustion of powdered boron, boron powder to improve the combustion efficiency of support. Powder of boron and oxygen combustion quality the same as growth per unit weight of the mixture increases the maximum temperature of the mixture of products means that the temperature increase. Column temperature combustion products to create the same quality of combustion, short of burning powder compound combustion baking plates early heat loss from the surface more. Along with the theoretical heat of combustion of burning powder of boron, so that measurement of oxygen to improve combustion efficiency, reducing the pressure. Air, reducing the oxygen pressure, the heat causes it to heat up excess oxygen with a higher increase in its temperature to heat the product, you can save.

 

Maximum temperature of the product, increasing the second stage of the reaction of boron particles, increase of oxidation quickly and completely, combustion efficiency increases. Improving the quality of combustion and combustion using powder and high temperature to reduce the pressure of oxygen, significantly improving the efficiency of the product, there are three ways to increase the burning powder of boron, boron powder, the temperature of combustion One of the factors that influence is very important for metal powder supplier.

 

Improving the quality of combustion substance, using the powder combustion, and reducing the oxygenation pressure are effective ways to improve the combustion efficiency boron powder and improve heat combustion test results. The gas temperature is an important factor to affect the combustion efficiency of boron powder. This model is consistent with boron two-stage combustion. Improvement of gas temperature increases the proportion of the second phase of the reaction for boron particles. It makes the oxidation reaction carried out more thoroughly, thereby improving the combustion efficiency for boron powder. With the temperature increases, the combustion efficiency of boron powder may be raised. But when the temperature reaches to a certain extent, improving combustion efficiency though the increasing temperature will become more difficult.Source:http://www.mhcmp.com
