Pressure difference

In a water boiler, draft is the difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage.[1] Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.[2]

Types of draft

Drafts are produced by the rising combustion gases in the stack, flue, or by mechanical means. For example, a boiler can be put into four categories: natural, induced, balanced, and forced.

• Natural draft: When air or flue gases flow due to the difference in density of the hot flue gases and cooler ambient gases. The difference in density creates a pressure differential that moves the hotter flue gases into the cooler surroundings.

• Forced draft: When air or flue gases are maintained above atmospheric pressure. Normally it is done with the help of a forced draft fan.

• Induced draft: When air or flue gases flow under the effect of a gradually decreasing pressure below atmospheric pressure. In this case, the system is said to operate under induced draft. The stacks (or chimneys) provide sufficient natural draft to meet the low draft loss needs. In order to meet higher pressure differentials, the stacks must simultaneously operate with draft fans.

• Balanced draft: When the static pressure is equal to the atmospheric pressure, the system is referred to as balanced draft. Draft is said to be zero in this system.

For the proper and the optimized heat transfer from the flue gases to the boiler tubes draft holds a relatively high amount of significance. The combustion rate of the flue gases and the amount of heat transfer to the boiler are both dependent on the movement and motion of the flue gases. A boiler equipped with a combustion chamber which has a strong current of air (draft) through the fuel bed will increase the rate of combustion (which is the efficient utilization of fuel with minimum waste of unused fuel). The stronger movement will also increase the heat transfer rate from the flue gases to the boiler (which improves efficiency and circulation).[3]

Drafting in steam locomotives

Since the stack of a locomotive is too short to provide natural draft, during normal running forced draft is achieved by directing the exhaust steam from the cylinders through a cone ("blast pipe") upwards and into a skirt at the bottom of the stack. When the locomotive is stationary or in a restricted space "live" steam from the boiler is directed through an annular ring surrounding the blast pipe to produce the same effect.

Two Types of FRP Cooling Tower

FRP Cooling Tower

What Is FRP cooling tower

FRP cooling tower meaning fiberglass reinforced plastic cooling tower innovated in a special way for heat exchange allowing air and water to come into contact with each other to the lower temperature of hot water. FRP cooling tower working is mechanically considered as heat rejection device where wase heat will be rejected to the atmosphere through the aid of a cooling water stream towards a lower temperature.

FRP cooling tower is commonly applied in oil refineries, chemical plants, petrochemical plants, thermal power stations and for cooling buildings through HVAC systems. This cooling towers could be either in natural draft or induced draft.

Cooling Tower Come in Different Types

Counterflow cooling towers, crossflow cooling towers, natural draft cooling towers, forced draft & induced draft cooling towers and industrial cooling tower.

What are FRP Cooling Towers Used for?

Basically, FRP cooling towers are designed for rejecting and disposing heat from chillers. It is less efficient for air cooled chillers than water cooled chillers because of the rejection of heat from water in the tower to near wet-bulb temperatures.

Six Reasons Why Fiberglass Products Are Used In Cooling Towers

Cooling towers are an important component of many industrial processes as they ensure efficient removal of excess and/or waste heat generated during various manufacturing processes. Most cooling towers have traditionally been built from wood, but it is not an ideal structural material given the long-term effects of water on wood. Here are six reasons why fiber-reinforced polymer structural profiles (FRP) are the best product for building cooling towers:
Corrosion resistance
Cooling towers are exposed to water and chemicals, which can corrode traditional materials. Fiberglass, also known as fiberglass-reinforced polymer (FRP) or fiberglass-reinforced plastic (GRP), has excellent corrosion resistance, making it an ideal material choice for cooling tower construction. It can withstand harsh conditions and prolonged exposure to moisture, chemicals and UV radiation without degrading like most traditional materials.
Lightweight and high strength
Fiberglass is a lightweight material with a high strength-to-weight ratio. This makes it easier to transport, handle and install cooling tower components. Despite its light weight, fiberglass is structurally strong and can withstand the loads and stresses encountered in cooling tower applications.
Design flexibility
Fiberglass can be molded into a variety of shapes and sizes, allowing flexibility in cooling tower design. It can be easily formed into complex geometries and customized configurations to optimize performance and efficiency. This flexibility allows manufacturers to create cooling towers tailored to specific project requirements and space constraints. Traditional wood cooling towers use 2x4, 2x6, and 4x4 treated lumber as well as plywood for decking. Pultruded fiberglass channels, square tubes and floors are simple one-to-one geometric alternatives to traditional wooden dimensions.
Heat insulation
Fiberglass has inherent thermal insulation properties. It helps reduce heat transfer, minimizing the loss of cooling efficiency in the tower structure. This insulating ability helps save energy and improves the overall performance of your cooling system.
Long life and durable
SINTA Cooling Tower Rebuilt Fiberglass has a long service life and requires minimal maintenance. It resists rot, rust and degradation, ensuring long-term durability of the cooling tower. Fiberglass cooling towers are known for their longevity and can withstand harsh environmental conditions without significant deterioration.
Cost-effectiveness
While the upfront cost of fiberglass cooling towers may be higher compared to other materials, the long-term cost benefits come from reduced maintenance needs, longevity and energy efficiency. Low maintenance requirements and extended service life help offset the initial investment.
Overall, fiberglass&#; combination of corrosion resistance, strength, design flexibility, insulating properties, longevity and cost-effectiveness make it a suitable material for cooling tower construction.

Conclusion

From quality to maintenance, FRP cooling towers has made its edge among other cooling towers. Aside from the strength and flexibility a fiberglass has to offer, low maintenance is also of good advantage when it comes to its structure.

Even when repairs will be required, still it can be done in just a matter of few hours. This the main reason why we recommend FRP cooling towers to our clients. Since quality and durability are what we always aim for to serve best to our clients, no matter if you need to move from one site to another, still the rigidity and durability of this FRP cooling tower will remain firm.

Thus, no other product we can recommend best but this FRP cooling tower we have available in the market.
