Select the (2) best choices that describe proper conditions for necessary complete combustion.

Large quantities of sulfur have to be supplied to the boiler.
Enough air must be supplied.
Transporting coal and ash via boiler stack
Enough time is given

Correct Answer(s)

A. Enough air must be supplied.
A. Enough time is given

Explanation

To achieve complete combustion, two conditions must be met: enough air must be supplied and enough time must be given. Sufficient air is necessary to provide the oxygen required for the combustion process. Without enough air, incomplete combustion may occur, leading to the formation of harmful byproducts such as carbon monoxide. Additionally, enough time is needed to allow for the complete oxidation of the fuel. If the combustion process is rushed, there may not be enough time for all the fuel molecules to react with the oxygen, resulting in incomplete combustion.

The purpose of codes & standards is to ensure boilers & pressure vessels are operated in a safe, efficient, & productive manner.

True
False

Correct Answer

A. True

Explanation

Codes and standards are established to provide guidelines and regulations for the safe operation of boilers and pressure vessels. These codes and standards outline the necessary requirements and procedures to ensure that these equipment are operated in a manner that minimizes risks, maximizes efficiency, and promotes productivity. By adhering to these codes and standards, organizations can ensure the safety of their personnel, prevent accidents, and optimize the performance of their boilers and pressure vessels. Therefore, the statement that the purpose of codes and standards is to ensure boilers and pressure vessels are operated in a safe, efficient, and productive manner is true.

Select the best choice below regarding statements about (BFW).Boiler Feedwater should be ______ and be kept at a pH value of _.

3.65
Acidic
Safe
Alkaline
10.5

Correct Answer(s)

A. Alkaline
A. 10.5

Explanation

Boiler Feedwater should be alkaline and be kept at a pH value of 10.5. This is because alkaline water helps to prevent corrosion in the boiler system and maintain its efficiency. A pH value of 10.5 is considered to be within the optimal range for preventing corrosion and ensuring the longevity of the boiler. Acidic water can cause corrosion and damage to the boiler, while a neutral pH may not provide enough protection against corrosion. Therefore, maintaining an alkaline pH of 10.5 is necessary for the safe and efficient operation of the boiler.

What is mixed with Sulphur dioxide (SO2) in order to produce an acid or, an acidic substance?

Coke
Limestone
Sulphuric Acid
Water

Correct Answer

A. Water

Explanation

Water is mixed with Sulphur dioxide (SO2) in order to produce an acid or an acidic substance. When water reacts with SO2, it forms sulfurous acid (H2SO3), which is a weak acid. This reaction occurs when SO2 dissolves in water, and it is an important step in the formation of acid rain. Therefore, water is the correct answer in this case.

Which hazard symbol displays a type of gas tank associated with it?

Flammable & Combustible
Poisonous & infectious
Compressed Gas
Biohazardous & Infectious

Correct Answer

A. Compressed Gas

Explanation

The correct answer is Compressed Gas. The symbol for Compressed Gas typically features a gas cylinder, indicating that the hazard is associated with pressurized gas containers. This symbol is used to identify substances that are stored under high pressure and can potentially explode or cause other hazards if mishandled. Flammable & Combustible, Poisonous & Infectious, and Biohazardous & Infectious symbols represent different types of hazards and are not specifically associated with gas tanks.

Select the best (2) statements below to the following question.The first boiler was made in the year , and it was called the boiler.

1895
1234
HRT Boiler
Haycock
1720

Correct Answer(s)

A. Haycock
A. 1720

Explanation

The correct answer is "Haycock, 1720". This answer is supported by the fact that the question asks for the name of the first boiler and the year it was made. The option "Haycock" refers to a type of boiler, and "1720" is the corresponding year. This suggests that the Haycock boiler was the first boiler made in the year 1720.

When a worker is injured on the job, who is responsible for the recovery upon returning to his/her workplace?

The co-workers
The Chief Engineer
The leading Supervisor
Paramedics
Police Officer

Correct Answer

A. The leading Supervisor

Explanation

The leading Supervisor is responsible for the recovery of a worker who is injured on the job upon returning to the workplace. This is because the leading Supervisor is typically in charge of overseeing the safety and well-being of the workers, and is responsible for ensuring that appropriate measures are taken to support the injured worker's recovery and reintegration into the workplace.

When the pressure in the safety valve is too high, the spring will lift off the seat.

True
False

Correct Answer

A. True

Explanation

When the pressure in the safety valve exceeds a certain threshold, the spring inside the valve will lift off the seat. This is because the spring is designed to release excess pressure and prevent any potential damage or explosion. Therefore, the statement "When the pressure in the safety valve is too high, the spring will lift off the seat" is true.

How are chemicals supplied to the boiler water?

Mechanical Declaration
Filteration
Pressure Filters
Displacement Motor Driven Pump
Water softening

Correct Answer

A. Displacement Motor Driven Pump

Explanation

Chemicals are supplied to the boiler water through a displacement motor-driven pump. This type of pump uses a mechanical mechanism to displace the chemicals and deliver them to the boiler water. It is a reliable and efficient method of supplying chemicals, ensuring that the correct amount is delivered consistently. Other options such as mechanical declaration, filtration, pressure filters, and water softening are not directly related to the supply of chemicals to the boiler water.
