How Does a Chimney Work?

Nowaays, almost all households have a kitchen chimney. They keep your kitchen clean and make your cooking experience better. Have you ever wondered how does a chimney work? Well, there is a very efficient and effective system to make this appliance work.

All the heat, dust, smoke, and oil are removed from your kitchen when you turn on the chimney. While the oil get collected in the filters of the chimney, the heat and smoke are let out through the duct attached to the chimney. They removal of these also keeps you from inhaling potentially harmful substances that might evaporate while you are cooking.

Without further ado, let’s take a look at answer to how does a chimney work.

How Does A Chimney Work?

Your chimney gathers all the unnecessary vapors and particles from your kitchen. This keeps it from becoming greasy and makes your cleaning job a lot easier. Besides, you are also protected from fumes. Chimneys are especially helpful if you tend to cook oil and spicy food.

While you are cooking, two types of components are let out. These are oil and grease particles and other evaporation substances that are let out in the form of heat, vapor, and smoke. All of this is readily sucked in by the chimney. The oil and grease particles get collected on the mesh filter while the smoke is let out through the pipe.

Types of Chimneys

To better understand the answer to how does a chimney work, you must know about the different types of chimneys available. They can be broadly divided into two categories: ducted and ductless.

The main difference between these two types lies in how they work.

Ducted Chimney

As in the name, these chimneys come with a duct. This duct works to pull out all the smoke and heat from your kitchen and expels it to the air outside. The filters in these chimneys can be washed as cleaned if too much grease gets accumulated in them. Although ducted chimneys are more expensive in the intial run, they have low maintenance cost.

A ducted chimney comes with an in-built motor, PVC pipes, and a ducting system that needs to be fitted into the very brick and mortar structure of your home. You will require experts for proper installation.

You should install it directly above your stove for the best effectiveness. They have more suction power than ductless chimneys and can absorb heat to prevent condensation around your kitchen. This is why they also help your kitchen not heat up too much, which can be uncomfortable.

Ductless Chimneys

A ductless chimney contains an additional carbon filter. This makes its maintenance costlier. These carbon filters are not washable and how to changes regularly. However, the initial cost, especially installation, are quite less.

Ductless chimneys do not expel the air and steam outside. Instead, they purify it and return it to your kitchen. These chimneys have two sets of filters. The first one stops the grease and oil residues. The carbon filter, which comes next, filters out the smoke and moisture remnants.

The clean air is then returned to the kitchen. These can be considered more helpful for the environment. However, they cannot regulate the temperature of your kitchen, and the heat can make you uncomfortable after a while.

Types of Filters in Kitchen Chimney

As we have seen before, all chimneys come with filters that help them absorb all the unnecessary particles present in your kitchen. There are majorly three types of filters. Take a look at them below.

Mesh Filters

Mesh filters are very popular and are mostly used in ducted chimneys. They mesh of the filters is usally made of either stainless steel or aluminum. It is a multi-layered structure. Filters made from stainless steel are costlier than their aluminum counterparts.

The small pores of the mesh retain all the oil and grease particles as the vapors from your stove pass through it. The remaining air contains other components, such as moisture, smoke, and carbon. This is expelled outside through the ducts of the chimney.

Stainless steel mesh filters are costiler, but they are easier to clean. On the other hand, aluminum ones need care to be maintained well. However, mesh filters, in general, are not very suitable for kitchen that cook a lot of oily and greasy food. The pores of the mesh get easily clogged. Once this happens, the airflow will not be smooth or effective.

Baffle Filters

Baffle filters work in a way that changes the air that flows through it. It is made of layers of aluminum or steel above each other to do this. These filters use a “cut and chop” technique. This is a unique mechanism that separates the food and oil particles from other components present in the air.

The food and oil particles are retained in the filter while the remaining smoke is expelled out through the pipes. This filter in made of multiple curved surfaces overlapping each other. The separation process ensures that the oil and food particles do not hamper the passage of smoke and air. It is a very efficient process.

This also makes it well suited to shops that sell deep-fried and greasy food. Plus, these filters can be easily cleaned with regular dishwashing liquid. Therefore, they are also cheap and easy to maintain. Nevertheless, they are well-built and durable. They are suitable for all types of kitchens.
