10+ ITD Cementation India Interview Questions and Answers

Boiler efficiency is a measure of how effectively a boiler converts fuel into heat energy. Improving efficiency in wood boilers can be achieved through proper maintenance, insulation, and combustion optimization.

• Boiler efficiency is calculated by dividing the heat output by the heat input and multiplying by 100 to get a percentage.

• To improve efficiency in wood boilers, regular cleaning and maintenance of the boiler and heat exchanger are essential.

• Insulating the boiler and pi...read more

Water chillers come in various types such as air-cooled, water-cooled, and evaporative chillers, each with specific design considerations.

• Air-cooled chillers use air to remove heat from the refrigerant, making them suitable for outdoor installation but less efficient than water-cooled chillers.

• Water-cooled chillers use water to remove heat from the refrigerant, offering higher efficiency but requiring access to a water source for operation.

• Evaporative chillers combine water e...read more

• Fluidized bed reactors are used for gas-solid or liquid-solid reactions...read more

Preventive maintenance involves regular inspections and maintenance to prevent breakdowns, while breakdown maintenance is performed after a machine or equipment has already failed.

• Preventive maintenance is scheduled and planned in advance to avoid unexpected breakdowns.

• Breakdown maintenance is reactive and performed after a machine has already failed.

• Examples of preventive maintenance include regular oil changes for vehicles and routine equipment inspections.

• Examples of break...read more

The different types of maintenance include preventive maintenance, corrective maintenance, predictive maintenance, and proactive maintenance.

• Preventive maintenance involves regularly scheduled inspections and maintenance to prevent breakdowns.

• Corrective maintenance is performed after a failure occurs to restore equipment to working condition.

• Predictive maintenance uses data and analytics to predict when maintenance should be performed based on the condition of the equipment.

• P...read more

HARPC and PCQI are food safety regulations in the US.

• HARPC stands for Hazard Analysis and Risk-Based Preventive Controls. It requires food facilities to identify and address potential hazards.

• PCQI stands for Preventive Controls Qualified Individual. It is a certification for individuals responsible for developing and implementing food safety plans.

• Both HARPC and PCQI are requirements under the Food Safety Modernization Act (FSMA) in the United States.
