Pros and Cons of Water Tube Boilers

In this post, ZBG Boiler will help you learn some basic pros and cons of the water tube boiler.

Before we start let’s know about the working principle of a water tube boiler and it will help you to understand its pros and cons clearly.

WATER TUBE BOILER WORKING PRINCIPLE:

In Water Tube Boiler water will be heated inside the Boiler Tube and heat will pass around the Tubes. Generally, heat passes from the boiler Furnace or Combustion Chamber to around the Boiler Tube. There are some other components is present with the boiler like Economizer, Air Pre-Heater, Steam Drum, Feed Water Pump, Steam Re-Heater. This type of boiler can use Oil and GAS in the Combustion Chamber.

When Feed Pump started to supply the feed water then, water converted into saturated steam. This saturated steam becomes a full super-heated steam by Super Heater and Steam Re-heater. Then super-heated steam supply to the prime mover. Now let’s go and find out the advantages and disadvantages of a Water Tube Boiler.

PROS OF WATER TUBE BOILER:

Operation: Operating a Water Tube Boiler is safe and easy.

Hitting Surface: It has more hitting surface and has many water tubes that heat the feed water.

Work Efficiency: This boiler has great work efficiency. We can control its heating process by controlling the amount of water supply in the water tube.

Small Steam Drum: This type of boiler has a small size steam drum. For this reason, we can use the generated steam at the pressure from 40 kg to 140kg/cm.

Flue GAS: In Water Tube Boiler flue GAS flows vertically.

Movement: It is easy to mover Water Tube Boiler from one place to another place.

Space: Water tube boiler required less space for installation.

CONS OF WATER TUBE BOILER:

Water Tube Damage: Boiler Tube can be damaged if there is any dust in the feed water. Because it blocks the water circulation. The deposition of salt and sediments in the inner surface of the Water Tube is a common problem for this type of boiler.

Water Level: Water Tube Boiler uses less water and for this reason, the water level needs to check randomly. A makeup water pump is used for supplying the necessary water.

Maintenance: Maintenance cost of water tube boiler is high.
