Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

How dangerous is it if your boiler pressure is well high

if you're boiler manual says it's maximum pressure is at or below 3 bar then fair enough (virtually all boiler manuals are available online), but every boiler installation should have a pressure relief valve that's set to relieve pressure before it becomes dangerous anyway, so it's very unlikely to be at a dangerous level.
