The upper part of the air collecting cavity communicates with the air supply ring. A separating plate is provided in the unit air supply channel and divides the unit air supply channel into upper and lower air flues. The upper air flue communicates with the cavity of the air supply ring. The lower air flue communicates with the air collecting cavity.
FAN BRAKE CONTROL SYSEM
A fan brake system for controlling an industrial fan system, the fan brake system including a fan brake having a brake pad movable on the fan brake to selectively engage the fan system. An actuator including a motor can be operable to cause the fan brake to perform a braking procedure on the fan system to resist rotational movement of the fan system. A controller can be communicated with the actuator, the controller operable to selectively cause the actuator and the fan brake to perform the braking procedure, wherein the controller is operable to monitor and control power being supplied to the motor of the actuator during the braking procedure to maintain a torque output of the motor according to a predetermined torque profile during the braking procedure.
DIRECT-DRIVE FAN SYSTEM WITH VARIABLE PROCESS CONTROL
Embodiments of a direct-drive fan system and a variable process control system are disclosed herein. The direct-drive fan system and the variable process control system efficiently manage the operation of fans in a cooling system such as a wet-cooling tower or air-cooled heat exchanger (ACHE), HVAC systems, mechanical towers or chiller systems.
Passive containment cooling system including multiple condensing stages and catalyst
A passive containment cooling system (PCCS) condenser, for reducing some non-condensable gases in the PCCS, includes a first and a second stage condenser that each include channels in fluid communication between an inlet and an outlet header. The inlet header of the first stage condenser is configured to receive a fluid mixture through a first inlet opening. The channels are configured to condense water from the fluid mixture flowing through the channels from the inlet header to the outlet header, respectively, of the first and second stage condenser. The PCCS condenser includes a catalyst in at least one of the outlet header of the first stage condenser or the inlet header of the second stage condenser. The catalyst catalyzes a reaction for forming water from hydrogen and oxygen in the fluid mixture. The outlet header of the second stage condenser is in fluid communication with a combined vent-and-drain line.
Induced draft air-cooled condenser
Air-cooled condensers and air-cooled condenser streets for condensing exhaust steam from a turbine are disclosed. An example air-cooled condenser street includes one or more rows of V-shaped heat exchangers. Each row includes a main steam manifold to introduce exhaust steam into tube bundles that are placed in an inclined position such that condensate formed in the bundles flows back by gravitation to the main steam manifold. Top steam manifolds are connected to the upper end of respectively each of the tube bundles of the air-cooled condenser street. The series of parallel top steam manifolds are forming a support assembly for supporting one or more fan decks. The fan decks support a plurality of fans to induce an air draft in the V-shaped heat exchangers.
