I manage emergencies during failure by following established protocols, coordinating with team members, and prioritizing safety.

• Immediately assess the situation and determine the extent of the failure

• Activate emergency response procedures and notify relevant authorities

• Coordinate with team members to address the issue efficiently

• Prioritize safety of personnel and equipment

• Communicate effectively with all stakeholders throughout the process

Interlocks in a boiler turbine are safety mechanisms that prevent unsafe conditions and protect equipment.

• Interlocks ensure proper sequencing of operations in the boiler turbine

• They prevent unsafe conditions such as overpressure, low water level, or flame failure

• Examples of interlocks include low water level shutdown, high steam pressure trip, and flame failure detection

• Interlocks help protect equipment from damage and ensure safe operation of the power plant

Boiler efficiency is the ratio of energy output to energy input. It can be calculated using various methods.

• Boiler efficiency is important for reducing fuel consumption and emissions.

• It can be calculated using the direct method, indirect method, or heat loss method.

• Direct method involves measuring all the energy input and output parameters.

• Indirect method involves measuring all the energy input parameters and calculating the energy output based on the heat balance equation.

Boiler water parameters are crucial for efficient and safe operation of a power plant.

• Boiler water parameters include pH level, conductivity, dissolved oxygen, and total dissolved solids (TDS).

• Maintaining proper pH level helps prevent corrosion and scale formation.

• Conductivity measurement indicates the level of impurities in the water.

• Dissolved oxygen should be minimized to prevent corrosion.

• TDS measurement helps monitor the concentration of dissolved solids in the water.

• Regu...read more

Steam turbine bearing clearance is the gap between the bearing and the shaft.

• Bearing clearance is important for proper lubrication and to prevent damage to the bearing and shaft.

• Clearance can be adjusted by shimming or machining the bearing housing.

• Clearance should be checked regularly and adjusted as needed to maintain optimal performance.

• Excessive clearance can cause vibration and damage to the turbine.

• Insufficient clearance can cause overheating and premature wear of the b...read more
