Latent Heat Flow - Engineering ToolB

Example - Latent Heat Flow. A ventilation system transports 10000 m 3 /h of air through a building. The state of the make-up (supply) air is 0 oC and 100% relative humidity. From the Mollier diagram the humidity ratio - x - can be estimated to 0.0037 (kg h2o /kg dry_air).

Condensing Gas Boilers - TJs Radiant Heat & Plumbi

Condensing technology maximizes fuel utilization and reduces your heating bills. By capturing the portion of latent heat, which in conventional heating boilers is lost through the chimney, condensing boilers, like the Vitocrossal 300, use as much as 98% of the original energy input to heat your building. Viessmann Vitocrossal 300, CU3A

Boilers: controls and heat recove

[PDF]heat by recovering both sensible heat and latent heat of evaporation, cooling flue gases below the dew point. This heat is normally used to preheat the boiler’sfeed water and to supply low grade heating requirements. The materials of construction ensure that the …

Water-tube or fire-tube condensing boiler, which is t

Condensing boilers achieve higher efficiencies by condensing the water vapor that is produced during combustion and trapped in the flue gases. In conventional boiler technologies, the latent heat contained in the water vapor is allowed to escape through the flue vent.

DIFFERENCE BETWEEN SENSIBLE AND LATENT HEAT | Freed

LATENT HEAT This is the energy absorbed or released by a thermodynamic system during a constant temperature process. Examples include ice melting or water boiling. When a solid turns into a liquid (melts) or a liquid turns into a gas (evaporates), the loosening of …

What Are Sensible and Latent Heat & Why Do They Matter f

Latent heat is the heat the results from an increase or decrease in the amount of moisture held by the air. Specifically, it’s the amount of energy needed to cause a phase change (for our purposes, liquid-to-gas or gas-to-liquid) without changing the actual temperature of a substance.

Condensing theory – How do condensing boilers a

It was essentially energy that was escaping out the flue as water vapour. Making that vapour condense before it leaves the boiler is our way of recapturing that latent energy as heat. So, how do we maximise condensation? Condensation occurs when humid air comes in contact with a cooler surface.

Performance of Boiler: Effiency, Power and Heat Balance She

The factor is known as factor of evaporation and is usually denoted by Fe. Its value is greater than unity for all boilers. In S.I. units, the value of latent heat at a temperature of 100° C is 2256.9 KJ/kg.

Latent Heat of Steam - an overview | ScienceDirect Topi

So the water vapor in the flue gas does not condense, and therefore the latent heat of vaporization of this component is not recovered. The effective heat available for use in the boiler is a lower amount, which is less than the chemical energy stored in the fuel.
