Closed type acetylene gas generators, also known as "wet acetylene generator systems," are designed to convert calcium carbide and water into acetylene gas and carbide lime while maintaining safe operating pressure and temperature ranges. The primary function of these generators is to ensure a safe and efficient generation process by controlling the reaction between calcium carbide and water, which produces acetylene gas, heat, and a byproduct known as carbide lime
The mechanical integrity of these systems is crucial to prevent catastrophic releases of highly hazardous chemicals. To ensure this, a documented program of procedures, training, inspections, and tests is implemented, along with preventive and predictive maintenance based on good engineering practices and manufacturers' recommendations
Some key components typically found in acetylene generator systems include a calcium carbide fill cart, fill cart lifting device, generator feed hopper, calcium carbide feed system, acetylene generator vessel, water supply system, operation control system, safety relief system, agitator and/or grates, carbide lime discharge system, flashback protection, and an inert gas supply system .
Safety features are paramount in the design of these generators. For example, the Model 50 PS Portable Acetylene Generator by Rexarc includes a pressure relief valve that automatically opens if pressure builds up excessively for any reason. Additionally, a safety check and flashback arrester are incorporated to prevent any flashbacks from reaching the generator
In summary, closed type acetylene gas generators are engineered to provide a safe, efficient, and continuous supply of acetylene for various applications, with a strong emphasis on mechanical integrity and safety features to prevent hazardous chemical releases.
