Workflow in Salesforce automates business processes by defining a series of actions triggered by specific events.

• Workflows can automate tasks like sending email alerts, updating fields, or creating tasks.

• Example: A workflow rule can send an email to a sales manager when a lead's status changes to 'Qualified'.

• Workflows are triggered by specific criteria, such as record creation or updates.

• They help streamline processes,...read more

Sharing settings in Salesforce control data visibility and access for users and groups.

• Sharing settings determine how records are shared among users.

• There are three main types: Public Read/Write, Public Read Only, and Private.

• Example: In a Private sharing model, only record owners can view or edit their records.

• Role hierarchy allows users higher in the hierarchy to access records owned by users below them.

• Sharing rules...read more

Boiler water & steam quality, cooling system & water consumption, coal analysis as per IS standard.

• Boiler water quality refers to the purity of water used in boilers to prevent corrosion and scale buildup.

• Steam quality is the measure of the amount of moisture in steam, with higher quality steam having less moisture.

• Cooling system quality control involves monitoring water quality to prevent fouling and corrosion in the ...read more

The O2 analiger in a boiler is typically located in the flue gas stream.

• The O2 analiger is used to measure the oxygen content in the flue gas.

• It is important to monitor the oxygen levels in the flue gas to optimize combustion efficiency.

• The O2 analiger is usually installed in the boiler's flue gas duct or stack.

• It may be located at a specific distance from the boiler outlet to ensure accurate measurements.

• The O2 analig...read more

O2 analyzers before ESP and after APH can lead to inaccurate readings and operational inefficiencies.

• O2 analyzer placement affects measurement accuracy; incorrect positioning can lead to false readings.

• High dust load from ESP can interfere with O2 sensor performance, causing drift or lag in readings.

• Temperature fluctuations after APH can impact O2 analyzer calibration, leading to inconsistent data.

• Regular maintenance a...read more

Desuperheating line is used to reduce the temperature of superheated steam by injecting water or other cooling agents.

• Desuperheating line is typically located downstream of the superheater in a boiler system.

• It is used to control the temperature of the steam to prevent damage to downstream equipment.

• The location of the desuperheating line may vary depending on the specific boiler design and application.

• Examples of desu...read more

APH leakage is a problem in boilers that can lead to reduced efficiency and increased emissions.

• APH stands for Air Preheater, which is used to heat the combustion air before it enters the boiler.

• Leakage in the APH can result in loss of heat and reduced efficiency.

• Identifying the leakage involves inspecting the APH for visible signs of damage or leakage, conducting pressure tests, and monitoring performance parameters.

• C...read more

Types of losses in Boiler

• Heat loss through flue gases

• Heat loss through radiation and convection

• Incomplete combustion losses

• Blowdown losses

• Ash and unburnt losses

There are eight types of losses in a boiler.

• The eight types of losses in a boiler are: radiation, convection, exhaust, blowdown, incomplete combustion, unburnt fuel, ash, and moisture.

• Radiation loss occurs due to the heat radiated from the boiler's surface.

• Convection loss occurs due to the heat carried away by the flue gases.

• Exhaust loss occurs due to the heat carried away by the exhaust gases.

• Blowdown loss occurs due ...read more

Drum pressure drops in the area of steam generation and distribution.

• Drum pressure drop can occur due to steam leakage in the distribution system.

• Pressure drop can also happen in the steam generation process, such as in the boiler or heat exchanger.

• Other factors that can cause drum pressure drop include fouling or scaling in the system.

• Monitoring and maintaining proper drum pressure is crucial for efficient and safe op...read more
