Concept and Description

Intergas Rapid Plus operates on the fundamental principle of condensing boiler technology, which involves recovering latent heat from flue gases. This process is achieved through a secondary heat exchanger that extracts additional thermal energy from the exhaust streams, resulting in considerably improved fuel efficiency compared to traditional heating systems.

Core Principles and Mechanisms

• Condensing Process: Intergas Rapid Plus utilises a design in which the water vapour present in the exhaust is cooled below its dew point, releasing latent heat that preheats the cold feed water. This refrigeration-like process boosts thermal efficiency and reduces energy wastage.
• Modulating Burner Technology: The modulating burner adjusts its flame intensity in real time based on the heating demand. This dynamic response ensures that the boiler operates at its optimal efficiency, reducing cycling losses and maintaining steady output.
• Digital Control Integration: Advanced control systems enable precise regulation of input parameters. These digital interfaces provide real-time feedback on operational performance, including temperature, pressure, and combustion efficiency.
• Safety Devices: Safety is enhanced through the inclusion of a Temperature and Pressure Relief Valve (TPRV) and a Thermostatic Mixing Valve (TMV), which work together to manage overpressure and prevent scalding risks. An expansion vessel is also employed to accommodate pressure fluctuations, ensuring stable operation under varying conditions.

Technical Composition

Intergas Rapid Plus is composed of several integrated modules:

• Combustion Chamber: Optimised to allow complete combustion of natural gas while capturing residual heat through a secondary heat exchanger.
