Diphenyl Steam Generator: The Core Equipment for Efficient Industrial Heating

1. Overview of Diphenyl Steam Generator

The diphenyl steam generatorhttps://8ruiyan.com/en/boiler-products/ is a specialized heating device that uses diphenyl or its mixtures (such as diphenyl-diphenyl ether) as a heat transfer medium. It is widely used in industrial fields requiring stable high-temperature heat sources. Through the vaporization-condensation cycle of diphenyl, it achieves efficient heat energy transfer, providing reliable thermal support for industries such as chemical and pharmaceutical production.

2. Core Working Principle

The operation of a diphenyl steam generator is based on the phase change principle of the heat carrier:

Heating and Vaporization: Liquid diphenyl is heated to its boiling point (approximately 255°C for pure diphenyl, up to 400°C for mixtures) in the heating unit, converting it into high-temperature steam.
Steam Transport: The high-temperature steam is delivered to heat-using equipment via insulated pipelines.
Condensation and Heat Release: The steam condenses within the heat-using equipment, releasing significant latent heat.
Return and Regeneration: The condensate returns to the generator via gravity or circulation pumps, completing the closed-loop cycle.

3. Key System Components

The system consists of five main modules:

Heating System: Electric/gas heating modules providing initial energy
Evaporation Unit: Specially designed vaporization chamber
Heat Exchange System: Includes steam distributors and condensation devices
Fluid Circulation System: High-temperature resistant pumps and specialized piping
Intelligent Control System: Integrated monitoring of temperature, pressure, and flow parameters
