The rotation direction of burning tangential circle in a 1 025 t/h boiler was contrary to the designed direction.Based on the numerical simulation of flow inside the combustor and momentum balance calculation for in-furnace aerodynamic field
that the momentum moment of the furnace centre was in the opposite rotation direction of designed tangential circle was considered as the main reason.Thus
the pressure of primary air
secondary air and tertiary air were adjusted to regain the tangential circle direction.Moreover
after transforming the original reversed baffle WR burner into the bias combustion pulverized coal burner with window-shades type concentrator
