ABSTRACT:
A heating unit (14) includes a flame holder (2) that has a plurality of randomly distributed pores and comprises at least about 50 wt % ceramic particles that have an emissivity of at least about 0.7. The heating unit (14) also has means for conveying a fuel/air mixture to the flame holder (2), means (18) for igniting the fuel/air mixture so it forms a flame in proximity to the flame holder, means (20) for transferring heat from the flame to a heat transfer medium, and means (26) for exhausting combustion products from the heating unit. A fuel/air mixture may be directed through the flame holder (2) and burned to form a flame in proximity to the flame holder such that the flame and flame holder interact to produce emissions of less than about 10 ng/J NO.sub.x.
