ABSTRACT:
A variety of essentially circulr-planform fire grates having ash discharge openings therein and intimate-contact preventing means thereon is presented. The intimate contact preventing means for the fire grate having upper surface contour of fluctuation-free profile in the circumferential direction of the fire grate comprises first fluctuation-free-bottom spider-web-planform fins having fin upper surface of fluctuation-free profile and second fluctuation-free-bottom spider-web-planform fins having fin upper surface of fluctuational profile. The intimate contact preventing means for the fire grate having upper surface contour of fluctuational profile in the circumferential direction of the fire grate comprises first fluctuational-bottom spider-web-planform fins having fin upper surface of fluctuation-free profile and second fluctuational-bottom spider-web-planform fins having fin upper surface of fluctuational profile. Also presented are generally polygonal-planform stationary fire grates having ash discharge openings therein and intimate-contact preventing means. The intimate contact preventing means for the fire grate having upper surface contour of fluctuational profile in one Cartesian coordinate direction comprises first fluctuational-bottom straight fins having fin upper surface of fluctuation-free profile and second fluctuational-bottom straight fins having fin upper surface of fluctuational profile. The intimate contact preventing means for the fire grate having upper surface contour of fluctuation-free profile in one Cartesian coordinate direction comprises first fluctuation-free-bottom straight fins having fin upper surface of fluctuation-free profile and second fluctuation-free-bottom straight fins having fin upper surface of fluctuational profile.
