What Is a Fall Arrest System?

A Fall Arrest System is a safety system designed to maintain the safety of highways over an extended period.

In the event of damage to noise barriers installed on highways due to incidents such as car accidents, a secondary disaster may occur if the noise barriers fall onto railways, local roads, or residential houses beneath overpasses. To prevent such incidents, a safety device is implemented using fall prevention wire ropes to secure the noise barriers and prevent them from falling.

The fall prevention wire ropes absorb the impact energy when the noise barriers fall, preventing them from impacting the road surface, rotating, or causing secondary accidents. Constructed with high-impact resistance and excellent durability, these components significantly contribute to the long-term safety of highways.

What Is an Economizer?

An economizer is a device designed to recover heat from exhaust gases for preheating boiler feedwater in heating systems.

The operational principle involves the transfer of heat from exhaust gases to the feedwater through a heat exchanger. This process preheats the feedwater, improving the overall energy efficiency of the boiler system.

Economizers are primarily used in various settings, including power plants, factories, buildings, and apartments. Their implementation leads to fuel savings and reduced exhaust emissions. There are two main types: the heat exchanger method, which uses tube-type heat exchangers, and the heat recovery boiler method, which employs plate-type heat exchangers.

The advantage of relatively low-cost implementation makes economizers an environmentally friendly choice, contributing to both energy savings and reduced emissions. When using economizers, it is crucial to select the appropriate model based on performance and specifications, ensure correct installation, and prioritize safe usage.

What Is a Downdraft Table?
