Understanding the Oil Fired Hot Water Boiler: Technical Parameters and Specifications

An oil fired hot water boiler, sometimes referred to as an oil fired hot water furnace or oil burning water heater, is an enclosed vessel in which water is heated, circulated, and then used for various applications such as space heating, domestic hot water, or industrial processes. These boilers utilize various types of fuel oil (e.g., light oil, heavy oil) which is atomized and ignited in a combustion chamber, transferring heat to the water circulated through tubes or within the boiler shell.

Key Technical Parameters:

When considering an oil fired hot water boiler for sale, several technical parameters are crucial for selecting the right model for your specific needs:

• Thermal Capacity (Heat Output): Measured in BTU/hr, kW, or Gcal/hr. This is the primary indicator of the boiler's heating capability. Typical ranges can vary from small commercial units (e.g., 500,000 BTU/hr) to large industrial systems (e.g., 20,000,000 BTU/hr or more).
• Working Pressure: The maximum allowable pressure within the boiler, usually expressed in Bar or PSI. Hot water boilers typically operate at lower pressures than steam boilers, often ranging from 0.7 MPa (100 PSI) to 1.6 MPa (232 PSI).
• Design Temperature: The maximum water temperature the boiler is designed to handle, typically up to 180°C (356°F) for industrial hot water applications.
• Efficiency: Represents how effectively the boiler converts fuel energy into useful heat, expressed as a percentage. Modern oil fired hot water boiler systems can achieve efficiencies exceeding 90% (lower heating value, LHV) or even 95% with condensing technology.
• Fuel Type: Specifies the type of fuel oil compatible with the boiler (e.g., light oil/diesel, heavy oil/furnace oil).
• Burner Type: Describes the combustion technology, which influences efficiency and emissions. Common types include atomizing burners (pressure jet, rotary cup) and forced draft burners.
• Boiler Type: Fire tube or water tube. Fire tube boilers pass hot gases through tubes surrounded by water, while water tube boilers circulate water through tubes surrounded by hot gases. Fire tube boilers are common for hot water applications due to their robust design and ease of maintenance.
• Emissions Data: Information on NOx, CO, and SOx emissions, critical for environmental compliance.
• Footprint and Weight: Important for installation planning and space requirements.
• Control System: Features of the automated control panel, including PLC (Programmable Logic Controller) integration, touchscreens, safety interlocks, and remote monitoring capabilities.

Below is a typical product specification table for a range of oil fired hot water boiler for sale models, demonstrating the variety available to meet different industrial demands:

Model Series	Rated Thermal Capacity (MW)	Working Pressure (MPa)	Design Temperature (°C)	Thermal Efficiency (≥ %)	Fuel Consumption (kg/hr) (Approx. Light Oil)	Footprint (L×W×H) (m) (Approx.)	Weight (tons) (Approx.)
