The expression of the pressure difference between inside and outside of a chimney shows that it has a term which is the height of the chimney. To achieve sufficient pressure difference between two points or to attain enough natural draught we have to increase the height of the chimney which is not always practical in the view of cost-effectiveness. In those cases, we have to think about artificial draught instead of natural draught. We can achieve artificial draught, mainly with two methods. One

Variety of materials are used for constructing Cooling Tower structures. Materials like fiber glass are used for constructing package cooling towers. However for field erected cooling towers material like steel, fiber glass, redwood and concrete and be used depending upon the project location and client preference.Plus and minuses of each cooling tower material is given below:Wood:Redwood as a material in cooling tower was used in 70’s and 80’s for small capacity cooling towers. Now a days becau

The boiler produces steam. If we utilize, a small portion of the pressurized steam for producing draught in a boiler system then we call the draught as steam jet draught. As the steam, causes the draught, generated in the boiler itself, there will be no need for extra electric power to run draught fans. Steam jet draught is a straight forward form of draught system in a boiler. No demand for additional electricity for running the draught fans hence reducing the cost of the system.Construction of

Purpose of a cooling tower is to reduce the temperature of circulating hot water to re-use this water again in the boiler. This hot water is coming from the condenser.How Cooling Tower Works?Hot water is coming at the inlet of the tower and pumped up to the header. The header contains nozzles and sprinklers which is used to spray water, and it will increase the surface area of water. After that, water comes to PVC filling; it used to reduce the speed of water. At the top the cooling tower, fans

Draught is the pressure difference which causes a flow of air or gases from one point to another point in the boiler system. Draught is required in a boiler system mainly due to two reasons. To supply sufficient air for completing the combustion. To remove flue gases from the system after combustion and the heat exchange.There are two types of draught applied to the boiler system. The natural draught The forced draughtWe will discuss here in this article about natural draught. The natural draugh

A natural draft cooling tower is a type of heat exchanger that cools water by direct contact with air. It is used in power plants, oil refineries, petrochemical plants, and natural gas plants to remove excess heat from the circulating water system. A natural draft cooling tower relies on the principle of convective flow to provide air circulation, without the need for fans or other mechanical devices. The airflow is driven by the density difference between the warm and moist air inside the tower

A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature. Cooling towers are widely used in industrial processes that require heat removal, such as power generation, refrigeration, air conditioning, and chemical processing. Cooling towers can be classified into different types based on their airflow, water flow, heat transfer method, and shape. Some common types of cooling towers are natural draf

There are mainly three types of jet condensers. Low level condenser. High level condenser. Ejector condenser.Low Level CondenserHere condenser chamber is placed at low elevation and overall height of the unit is low enough so that the condenser may be directly placed beneath the steam turbine, pump or pumps are required to extract the cooling water condensate and air from the condenser.Low level jet condensers are of two types- Counter Flow Parallel Flow Jet Condenser.Let discuss this jet conden

What is a Steam Condenser for a Turbine?A steam condenser for a turbine is a device that converts the low-pressure exhaust steam from asteam turbineinto water by using cooling water. The main function of a steam condenser for a turbine is to maintain a low back pressure on the exhaust side of the steam turbine, which increases the efficiency and output of the power plant.The exhaust steam from the turbine has to expand to a large extent to convert its available energy into mechanical work. If th

A surface steam condenser is a device that cools and condenses the exhaust steam from a steam turbine in a thermal power plant or other applications that use steam. The main purpose of a surface steam condenser is to increase the efficiency of the turbine by creating a low-pressure environment at the turbine outlet and to recover the pure water from the steam for reuse as boiler feed water.A surface steam condenser consists of a shell that contains a large number of tubes through which cooling w
