    摘要: A blower for a furnace is provided with an inlet guide to increase efficiency and pressure output of the blower. The blower includes a blower housing with an inlet opening and an outlet discharge opening. A cylindrical wall is provided around the inlet opening and projects into a hollow interior of the blower housing. A radial wall extends outward form the cylindrical wall toward the discharge outlet opening to prevent recirculation of gases from the outlet to the inlet during operation of the blower.

    摘要: A blower for a furnace is provided where the blower has an impeller that is configured to create a primary air flow of combustion air into the blower housing and a secondary air flow of cooling air through the blower motor. The primary air flow of combustion air into the furnace generates hot exhaust gases for a heat exchanger in the furnace. The secondary air flow cools the blower motor. The secondary air flow is mixed with the hot exhaust gases in the blower housing and cools the exhaust gases before being discharged from the blower housing. A control operates the blower for a time period after each combustion cycle to introduce ambient air into the exhaust flue and chimney to ensure the evaporation of any condensate forming from the products of combustion contained in the exhaust. The blower may be a variable or multi-speed motor so that a different motor speed may be used for combustion than for the run time after combustion.
