A Complete Guide to Oil-Fired Hot Water Boilers

By Boiler Philippines | July 25, 2025

Hot water is a vital need for industries and homes, especially in regions with colder climates. Bulk hot water production is only feasible with an oil-fired hot water boiler system.

Hot Water boiler Oil Fired System Drawing

 

What Is an Oil-Fired Hot Water Boiler System?

An industrial hot water boiler is a complex network of vessels enclosed in a metal container. It uses heat energy from fuel combustion to raise water temperature, which is then transported through pipes for industrial use.

 

Design of an Oil-Fired Hot Water Boiler

Unlike commercial systems, industrial boilers do not boil water but heat it to 220°F (beyond the standard boiling point of 212°F) due to increased internal pressure.

Key Design Features:

  • Compact and durable: Made from anti-corrosive metals like stainless steel.
  • Lightweight insulation: Aluminum silicate fiber lining for temperature and pressure resistance.
  • Shape options: Circular, vertical, or horizontal designs.

Components of an Oil-Fired Hot Water Boiler

Every boiler includes these core parts:

  1. Burner: Combusts fuel (oil, gas, or solid) to generate heat.
  2. Heat Exchanger: Transfers heat from combustion to water.
  3. Combustion Chamber: Space where fuel burns continuously.
  4. Control Systems: Automation tools for monitoring temperature, pressure, and alarms.

 

Accessory Parts (Optional):

  • Economizer
  • Circulation pump
  • Aquastat
  • Feedwater heater
  • Condenser

Types of Industrial Hot Water Boilers

1. Gas-Fired Boilers

  • Fuels: Natural gas, LPG, propane, or butane.
  • Most efficient but costly.

2. Oil-Fired Boilers

  • Fuels: Light oil, heavy oil, kerosene, red diesel.
  • Ideal where piped gas is unavailable.

3. Solid-Fuel Boilers

  • Fuels: Wood, coal, agricultural waste.
  • Lower efficiency but cost-effective.

4. Electric Boilers

  • 98% efficiency; requires stable power supply.

 

5. Vacuum Boilers

  • Operates under negative pressure for safety.
  • Energy-efficient and versatile for varying temperature needs.

 

 

How Does an Oil-Fired Hot Water Boiler Work?

  1. Fuel Intake: Oil is fed into the combustion chamber.
  2. Combustion: Heat is generated and transferred via the heat exchanger.
  3. Water Heating: Water circulates through tubes, absorbing heat.
  4. Distribution: Hot water is pumped to industrial systems.

Advantages of Oil-Fired Hot Water Boilers

  • Safety: Stainless steel construction and pressure-resistant design.
  • High Efficiency: Up to 98% with economizers/condensers.
  • Automation: Smart controls for temperature regulation and leak detection.

 

Safety Precautions

  • Wear protective gear.
  • Regularly check fuel/water levels and leaks.
  • Never leave the boiler unattended.

Maintenance Steps

  1. Inspect: Fuel lines, water supply, and heat surfaces.
  2. Revise: Professional check every 2 years.
  3. Clean: Remove residue and blockages.

Cost Range

  • Standard boilers: $9,000–$80,000 (capacity-dependent).
  • 5-ton boilers: $55,000–$98,000.

 

Why Choose Boiler Philippines?

With 40+ years of expertise, we provide:

  • Durable, lightweight boilers with aluminum silicate insulation.
  • Custom temperature control (10°C–90°C).
  • Microcomputerized systems for precision.

A Guide to Choosing the Best Boiler Grate Bars for Maintenance

  By , ,

How to Purchase the Right Boiler Grate Bars During Maintenance?

Boiler grate bars are critical components directly involved in fuel combustion, widely used in chain grate steam boilers, hot water boilers, thermal oil boilers, and other thermal equipment. To ensure the boiler operates efficiently, regular inspection and maintenance of the chain grate and its components are essential.

Common Chain Grate Issues and Solutions

  • Chain Grate Movement Failure: Large fuel particles or external forces can cause the grate to jam, leading to intermittent movement or complete stoppage. Severe cases may result in broken fuse links or damaged transmission mechanisms. Immediate inspection and troubleshooting are required

 

  • Chain and Gear Misalignment:Prolonged operation can cause significant wear, leading to misalignment. Timely chain replacement is necessary.

 

  • Chain Beam Bending: External forces or overload can bend the beams, requiring immediate replacement.

 

  • Grate Deviation During Operation: Improper adjustment of the front and rear axles during installation can cause unstable grate movement.

 

  • Fuel Coking on the Grate: Long-term use of low-quality coal or high-oil-content fuel can lead to caking on the grate surface. Regular cleaning is recommended.

Purchasing New Chain Grate Spare Parts

When replacing essential parts like grate bars, it’s crucial to provide suppliers with accurate details to avoid confusion. Below are key measurements for a 20t/h chain grate steam boiler:

1. Left and Right Boiler Grate Bars

Measure the length, width, height, and positioning dimensions. Note that left and right bars may look similar but have different installation orientations.

                        

2. Middle Grate Bar

Provide detailed measurements as illustrated.

                         

3. Large Grate (Fish Scale Type)

Due to variations between manufacturers and batches, measure the length, width, height, hole spacing, hole diameter, and other parameters.

                     

4. Chain

Specify the length, number of sections, thickness, and other requirements. For example, a 20m chain with 125 sections.

5. Boiler Slag Stopper/Ash Remover

Measure the arc length and the distance between endpoints.

6. Roller

Provide the overall length.

7. Bushing

Include outer and inner dimensions.

8. Shaft

Specify the dimensions and overall length.

9. Grate Buckle

Provide the end face diameter and connecting part diameter.

10. Side Seal Plate

Measure the overall length, height, and width, as designs vary.

Summary

By providing the above data to suppliers, you can easily purchase the correct parts. If unsure, feel free to contact Boiler Philippines for professional assistance.

The Essential Guide to Boiler Capacity and Its Units

  By

Understanding Boiler Capacity: Units, Calculations, and Selection Guide

Introduction to Boiler Capacity

When preparing to purchase a steam boiler, understanding boiler capacity is crucial for making an informed decision. Boiler capacity determines how much steam or heat energy your system can produce to meet your operational needs.

Types of Boiler Output

Different boiler types produce various forms of heat energy:

  • Steam boilers: Generate steam for industrial processes

 

  • Hot water boilers: Provide heated water for heating systems

  • Heat transfer oil boilers: Circulate thermal oil for high-temperature applications

 

  • Hot air boilers: Produce heated air for drying or space heating

 

Boiler Capacity Units

Different countries use various units to measure boiler capacity:

Boiler Type Common Capacity Units
Steam boilers ton/hr, kgs/hr, lbs/hr, BHP
Hot water boilers kW, kcal/h
Thermal oil boilers kW, MW, kcal/h
Hot air boilers kcal/h (with air volume in m³/h)

 

Capacity Conversion Guide

Standard conversion factors between common boiler capacity units:

Conversion Equivalent
1 ton/hour = 1000 kg/h
1 ton/hour = 12,000 Btu(IT)/hr
1 ton/hour = 2204.62 lbs
1 ton/hour = 646,500 kcal/h
1 ton/hour ≈ 700 kW (0.7 MW)
1 MW = 1000 kW

If you want to convert faster, please check the conversion tool below.

Boiler Pressure Classification

Industrial boilers operate at different pressure levels:

  • Low pressure: 10-15 psi (small household boilers)
  • Medium pressure: 16-1000 psi (0.1-3.83 MPa)
  • High pressure: Above 1000 psi

Operating temperatures typically range from 194°F to 842°F (90°C to 450°C).

 

Fuel Options

Modern boilers can utilize various fuel sources:

  • Oil
  • Natural gas
  • Coal
  • Biomass
  • Electricity

Consider fuel costs, environmental regulations, and equipment expenses when selecting your boiler.

 

Water Capacity Considerations

Boiler water capacity affects performance:

  • Large water capacity:
    • Longer startup time
    • Better load stability
    • Increased safety
  • Small water capacity:
    • Faster response to load changes
    • More sensitive to sudden demand increases
    • Higher risk of water shortage

As a general rule, water capacity should approximately match the boiler’s working capacity.

 

Boiler Selection Factors

When choosing a boiler, consider:

  1. Required capacity (steam output or heat energy)
  2. Operating pressure and temperature
  3. Fuel type and availability
  4. Space constraints
  5. Efficiency requirements
  6. Environmental regulations
