Natural draft and forced draft cooling systems

Natural draft and forced draft cooling systems are two types of cooling systems that are commonly used in industrial and power plants. Both systems are used to remove excess heat from equipment and processes, but they differ in the way that air is circulated.

Natural Draft Cooling System:

A natural draft cooling system uses the natural convection currents created by the difference in temperature between the hot exhaust gases and the surrounding atmosphere to circulate air through the cooling system. The warm air rises, and the cooler air is drawn in from below to replace it. The cooling tower is typically tall and has a large diameter, which allows for maximum air circulation. This type of cooling system is less energy-efficient than forced draft cooling but is less expensive to operate.

Forced Draft Cooling System:

A forced draft cooling system uses fans or blowers to force air through the cooling system. The fans or blowers create a positive pressure that forces the air to move through the system. The cooling tower is typically smaller in diameter and has a taller height than a natural draft cooling tower. This type of cooling system is more energy-efficient than natural draft cooling but is more expensive to operate. The choice between natural draft and forced draft cooling systems depends on several factors, including the size of the system, the ambient conditions, and the required efficiency. Natural draft cooling systems are typically used in smaller systems, while forced draft cooling systems are used in larger industrial and power plant applications. The type of cooling system used will have a significant impact on the energy consumption and operating costs of the plant.

Angle measuring instrument:- → The instrument which is used for measurement the slope of any object surface is called angle measuring instrument . →T here are 3 types of angle measuring instrument. ( I)Sine bar ( II)Clinometer ( III)Bevel Protector SINE BAR:- → sine bar is an angle-measuring instrument that measures slope of any object with the help of slip gases and a dial indicator. → it is a steel piece mounted over two hardened steel cylindrical roller having equal diameter. → To make it lighter in weight small holes are drilled along steel piece. Principle:- →The working of sine bar is based on the princiople of trigonometry. In this one roller is placed over combination of slip gauges and another is placed over table surfaces. →If H is the height of slip gauge c...

Evaporators – natural convection, forced convection types.

Evaporators are heat transfer devices used in refrigeration systems to remove heat from the surroundings and convert the liquid refrigerant into a vapor. There are two types of evaporators: natural convection and forced convection. Natural Convection Evaporators: Natural convection evaporators use the natural buoyancy of the vapor to circulate it through the evaporator. The liquid refrigerant flows through a series of tubes, and as it evaporates, the vapor rises to the top of the evaporator. This creates a temperature difference between the top and bottom of the evaporator, which creates a natural circulation of the refrigerant. Natural convection evaporators are typically used in small refrigeration systems or in applications where there is a low heat load. For...

Different types of business structures, Business Ideas and their implementation:- • Discovering ideas and visualizing the business • Activity map • Business Plan

Different types of business structures:- 1. Sole Proprietorship:- A sole proprietorship is the simplest and most common form of business structure. In this type, the business is owned and operated by a single individual. The owner has complete control over the business and assumes all liability for its debts and obligations. Some key features of a sol e proprietorship include: • Ownership: The business is owned by one person, known as the sole proprietor. • Liability: The sole proprietor has unlimited personal liability for the business's debts and obligations. This means that personal assets can be used to satisfy business liabilities. • Decision- Making: The sole proprietor makes all the decisions regarding the business's operations. • Taxes: The owner reports business income and expenses on their personal tax return. 2. Partnership:- ...
