Hot Water Generator

Typical Hot Water Generator Technical Specifications

1. Performance & Capacity

• Heat Output / Capacity: Usually expressed in kcal/hr or liters/hour e.g., 0.05 to 10 million kcal/hr for industrial steam-type systems.

• Flow rate: Up to ~125 m/hr depending on model and rating.

• Water storage/capacity: Some packaged units list capacities in liters (e.g., ~162 L).

2. Temperature & Pressure

• Max outlet temperature (hot water): Up to ~9095 C for most direct hot water generators.

• Pressurised models: Can handle higher temperatures depending on design and rating (up to ~140 C+).

• Operating pressure: Atmospheric or low-pressure up to several kg/cm in industrial systems.

3. Fuel Types & Combustion

• Fuels: Diesel (HSD/LDO), natural gas, LPG, coal, biomass, wood, dual fuel options.

• Burner system: Fully automatic pressure-jet or multi-block burners with flame monitoring.

• Electric options: Electric hot water generators use resistive heating elements with PID or thyristor control for temperature.

4. Efficiency & Heat Transfer

• Thermal efficiency: Ranges from ~85% up to ~95% (NCV basis) depending on design, insulation, and fuel type.

• Heat exchanger: Coil, shell-and-tube, or multi-pass designs to maximize heat transfer.
