The using and transformation in practice of Dongfang Boiler hedge burners.
Abstract：With the xinchang DG2060/26.15-Ⅱ2 hedge burner for research object, this paper puts forward a can solve the burner and heat-resistant, prevent grind with resistance from structure scheme to burner transformation. Charge before a wind, secondary air circulation section, namely, the backflow area all comply with the design requirements. Preliminary after transforming the operation shows that has transformed the stability of the burner, fire increases greatly, burner does not appear with burning wind ring off, for electric production safety and stability provides conditions.
