Your team started by assessing the boiler and steam network. You gathered the following information:The boiler operates at a pressure of 7 bar.The AF ratio is adjusted manually.The steam network is insulated, except at certain points where fittings and valves are presentNo visible steam leaks.The exhaust gas temperature is 330°C.The O2 percentage in the exhaust was found to be 8.5%.Maintenance is not regular.The boiler consumed 23,000 GJ of natural gas in 2022 (price of natural gas is JD 7.5/GJ). Prepare a short note (to be incorporated in the audit report which your team leader will compile) to provide your assessment of the boiler and steam system. Your contribution should include the following: 1. Estimation of current boiler efficiency.2. Measures that can be taken to improve the boiler efficiency.

Question

Your team started by assessing the boiler and steam network. You gathered the following information:

The boiler operates at a pressure of 7 bar.
The AF ratio is adjusted manually.
The steam network is insulated, except at certain points where fittings and valves are present
No visible steam leaks.
The exhaust gas temperature is 330°C.
The O2 percentage in the exhaust was found to be 8.5%.
Maintenance is not regular.
The boiler consumed 23,000 GJ of natural gas in 2022 (price of natural gas is JD 7.5/GJ). Prepare a short note (to be incorporated in the audit report which your team leader will compile) to provide your assessment of the boiler and steam system. Your contribution should include the following:
1. Estimation of current boiler efficiency.
2. Measures that can be taken to improve the boiler efficiency.
