求翻译：发现钝体高度变化时燃烧温度基本没有变化，但是高温区域的范围随钝体高度的增大而变大，分析了锅灶位置对燃烧器效率的影响是什么意思？

Combustion temperature in the discovery of the height variation of the bluff body has not changed, but the range of high-temperature region with the bluff body height increases and bigger, the stove, the location of the burner efficiency

Blunt body found at high combustion temperature changes is largely unchanged, but the areas of high temperature range with a blunt object height increases and the analysis of the larger, cookstoves, efficiency of combustion where the impact

Discovered the blunt body changes highly when the combustion temperature does not have the change basically, but the high temperature region scope high increased along with the blunt body increases, has analyzed the pot stove position to the burner efficiency influence
