Biasing SH panels can obviously improve the pressure distribution deviation on both sides in horizontal flue gas duct

eliminating the influence of reskleual rotating gas resulted from tangentially fired boiler

and making the flow resistance not to be comparatively increased. Hence

the existing equipments shouldn’t be changed to make the equipments’ cost to be heightened. The experiment shows that the new method to be simple

effective

and feasible. At the same time

it can effectively enhance the safe and economic level in operation of thermal power plants with high - capacity units.
