1 tons of coal-fired old boiler efficiency

1.2 Anthracite Coal Combustion

Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.

Boiler Efficiency - an overview | ScienceDirect Topics

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

Boiler Pressure Too High, Low, Keeps Rising, Dropping

Here's a rough idea of the fluctuations in boiler pressure that you really don't need to spend time worrying about…. 1 to 1.5 bars on your pressure gauge ⇨ normal pressure level when your central heating is switched off. Around 2 bars ⇨ normal pressure level when your boiler is active/heating up.
