Using CFD to design effective smoke and ventilation systems in power generation and energy from waste facilities

Posted by Conor Logan on 09/11/21 10:00

Power generation plants and energy from waste facilities, whatever their size, present several design challenges in relation to ventilation and smoke extraction.

With over 85 years in ventilation and smoke control design, manufacture and install, Colt has worked with numerous power generation and energy from waste facilities. To help us navigate the challenges presented by these complex projects, one of the key tools we use to assist with designing effective systems in power generation, is in-house computational fluid dynamics (CFD). Before we explain the benefits of CFD further, let’s take a look at some of the most common problems a designer working on a power generation project might encounter.

The anatomy of a smoke control system

Posted by Conor Logan on 14/10/21 11:00

While it’s often understood that the basic function of a smoke control system is to control the movement of smoke in a fire to help keep buildings and their occupants safe, we also frequently get asked what components go into designing an effective smoke control system.

To answer that question in simple terms, we can compare a well-designed smoke control system to a human body, as all the same basic elements are needed to keep each functioning properly:

  • Decision-making control panel (brain)
  • Sensors and detectors (eyes/ears)
  • Equipment and devices (muscles)
  • Cable Network (nervous system)
  • Power Supplies (cardiovascular system)

Smoke Control in buildings with atria

Posted by Conor Logan on 30/06/21 10:00

Many residential and commercial buildings feature atria as a design feature to create a light well or to incorporate lifts or stairs into the design in a visually aesthetic way. However, they also provide a passage whereby smoke and fumes resulting from a fire could easily spread up through the entire building and affect multiple floors. Therefore, having effective smoke control and suppression systems in place in buildings with atria is essential.

Smoke control in shopping centres: design approaches and challenges

Posted by Conor Logan on 08/06/21 10:00

In retail premises such as shopping centres, the Building Regulations have a strong emphasis on the provision of life safety systems such as smoke control.

A well-designed smoke control system should be able to maintain smoke free escape conditions at low level to allow the building to be evacuated with minimum risk of smoke inhalation, injury or death.

7 reasons why you shouldn't use HVAC control systems for smoke ventilation

Posted by Conor Logan on 02/06/20 10:00

Smoke ventilation systems today require sophisticated control systems with highly complex sequences of operation. HVAC control systems could be seen as a viable solution, as they can be extremely flexible and offer a high degree of programmability. However, while they may be adequate for simple applications, there are a number of issues that mean they do not deliver on all the functionalities needed for more complex schemes.

Here are 7 reasons why:
