Junkers Gas Calorimeter Full Set | Digital Model for Gaseous Fuel Calorific Value
The Junkers Gas Calorimeter is a highly specialized apparatus used for determining the calorific value (heat value) of combustible gases. This instrument, based on the established Junkers principle, is a non-recording and flow type of calorimeter. It is essential for quality control and research in fields dealing with gaseous fuels. This offering is a full set from the Junkers brand, packaged complete with all necessary measuring and control components, excluding the LPG gas cylinder required for operation.
Principle of Operation
The core function relies on the principle of combustion and heat transfer. The calorimeter operates by burning a known volume of gas and efficiently transferring the resultant heat to a continuously flowing stream of water. The rise in the temperature of a measured quantity of water is used to quantify the heat released.
The measurement is calculated by equating the heat liberated by the burnt fuel to the heat absorbed by the water and the apparatus. The fundamental calculation determines the calorific value using the relationship: Calorific Value of Gas X Volume of Gas = Volume of water X Rise in Temperature.
Key Components and Features
This full Junkers Gas Calorimeter set is designed to provide comprehensive measurement capabilities for gaseous fuels:
• Calorimeter Unit: The core device consists of the calorimeter itself, equipped with a burner, typically mounted on a tripod stand for stable positioning.
• Gas Flow Control: A non-recording Gas Flow meter (often 1 Liter capacity) is supplied to accurately meter the amount of gas entering the combustion chamber.
• Pressure Regulation: A crucial pressure governor is included to maintain steady gas flow conditions for repeatable results.
• Temperature Measurement: The apparatus includes a Digital Temperature Indicator/Controller featuring a P.T. 100 sensor for precise measurement of inlet and outlet water temperatures. Traditional models may include two thermometers.
• Accessories: The complete set comes with a burner set, a safety valve, rubber tubing (sometimes up to 4 meters), and a measuring jar (such as a 2 Liters jar) for collecting the flowing water.
Application Areas
The Junkers Gas Calorimeter is indispensable in various sectors where fuel efficiency and quality are analyzed:
• Petroleum and Gas Industries: Used extensively for determining the calorific value of fuels supplied.
• Power Generation: Crucial for Thermal Power Houses.
• Industrial Plants: Utilized in Coke Oven Batteries, Cement Industries, Steel Plants, and Fertilizer Industries.
• Research & Education: Essential equipment for Educational Institutes, research laboratories, and R&D centers
analyzing fuel and flue gases.
