Which component is designed to reduce lag time caused by forced draft blower inertia?

• A. Control pressure relay
• B. Steam flow rate relay
• C. Fuel air ratio relay
• D. Rate time relay

Answer: (B)

The steam flow rate relay is specifically designed to address issues related to lag time stemming from the inertia of the forced draft blower. In processes where air is introduced into a system for combustion, the response time of the blower can lead to delays in achieving the desired airflow relative to the steam demand. A steam flow rate relay helps to monitor and adjust the flow of steam based on current system requirements, ensuring that the response to changes in system demand is swift. This relay accounts for the inertia of the blower, allowing for better coordination between the steam production and the air supply, resulting in more efficient operation and improved response times. The other options, while they may play important roles in their own right, do not specifically target the issue of lag time associated with blower inertia. For instance, a control pressure relay generally monitors and maintains pressure levels, while a fuel air ratio relay ensures optimal combustion efficiency by balancing fuel and air supply. A rate time relay is focused on timing or rate control, rather than directly addressing the particular inertia issues of the forced draft blower system.
