Delta T Shutdown: The temperature rise across the heat exchanger has exceeded the set parameters for the boiler. Verify that the system is full of water and that all air has been properly purged from the system. Verify that the boiler is piped properly into the heating system. Check for voltage to the boiler pump motor on a call for heat.

The design of a condensing boiler enables a lot of this latent heat to be recovered by condensing the steam in the flue gases back to water (condensate), but this can only be achieved by getting the return water temperature down to 54 degrees C – the dew point of gases.

2019-5-11 · Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

An expandable commercial heating system. Something I see a lot on projects is the phased approach to purchase and installation. In particular when constructing a new residential building or mixed use development supplied by a heat network/energy centre.. Often only parts of the building are in use when it is first opened until they sell or lease the dwellings, offices or commercial units.

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.
