Cylindrical hood

Overview: The cylindrical hood is suitable for natural ventilation systems and not for mechanical ventilation systems. The local resistance coefficient of the cylindrical wind cap used for exhaust is Zeta=1.2 when there is wind and Zeta=0.61 when there is no wind. Our factory produces two types of cylindrical wind caps: fiberglass and steel, which meet the specifications of T611.

(1) Continuous discharge is also known as continuous discharge. It is a continuous discharge of boiler water from the steam drum. The purpose of this discharge is mainly to prevent the salt (or silicon) content in the boiler water from being too high, and it can also remove fine suspended water slag in the boiler water. The reason why continuous discharge is led out from the steam drum is because the salt content (or silicon content) of the boiler water in the steam drum is relatively high during the operation of the boiler hood.
(2) Regular discharge is also known as scheduled discharge. This discharge method involves regularly discharging a portion of the boiler water from a point in the boiler hood water circulation system (such as from the lower header of the water-cooled wall). The main purpose of regular sewage discharge is to remove water debris.
Regularly discharge pollutants for a short period of time, usually controlled within 0.5 to 1 minute. Long discharge time or excessive operation can greatly affect the safety of boiler hood water circulation.

Ordering Notice: When water droplets are not allowed in the room, a drip tray can be installed at the bottom of the air cap connection. If the user needs a matching drip tray, please indicate it when ordering.

Overview of spherical wind caps: Spherical wind caps are suitable for natural ventilation systems, with a spherical shape that is aesthetically pleasing and sturdy.
The local resistance coefficient of a spherical wind cap used for exhaust is 0.97 when there is wind and 0.58 when there is no wind. The spherical wind caps produced by our factory are made of fiberglass and have a colored adhesive coating on the surface. They are non corrosive, have a long lifespan, and are aesthetically pleasing. They can be made in various colors according to user requirements.
