Gas and Oil Fired Boilers

Gas and Oil Fired Boilers Built in Pakistan

Gas and oil fired boilers are clean, quick to start and easy to control. They are a good choice when your factory has a reliable gas connection, or when you need a backup boiler that can run on furnace oil or light diesel oil. AGK makes these boilers from 3 to 25 TPH in wet back and dry back fire tube designs, and in A, D and O-type water tube designs for higher capacity and pressure. Every unit is designed and built by our engineers in Sahiwal.

Fuels You Can Use

• Natural gas (SNGPL or SSGC connection)
• RLNG
• Light diesel oil (LDO)
• Heavy furnace oil (HFO)
• Dual fuel: gas with oil as backup

A dual fuel burner lets you switch to oil when gas pressure drops, so production does not stop.

Wet Back or Dry Back?

In a wet back boiler, the rear chamber is cooled by water. It is more efficient and needs less refractory work. A dry back boiler has a refractory-lined rear door, which is easier to open for cleaning and inspection. Our engineers will suggest the right option based on your load and maintenance team.

Planning for Rising Gas Prices

Gas prices and supply rules for industry in Pakistan keep changing. Many of our customers now keep a gas boiler for quick load and add a biomass boiler for base load, which lowers the total fuel bill. Others choose our biomass steam supply service and pay only for steam. If you already have an old gas boiler, our boiler engineering services team can check it for repair, upgrade or fuel conversion.

Where These Boilers Work Best

Our gas and oil fired boilers are used in textile finishing units, pharmaceutical plants, hospitals, hotels, food and beverage factories, dairies and chemical plants. They suit sites where space is limited, where clean operation is important, or where steam is needed quickly in the morning and for short shifts. Because there is no ash and no fuel storage yard, the boiler room stays clean and needs fewer staff.

Why Factories Choose AGK

• Local manufacturer with our own workshop in Sahiwal since 2002
• Boilers designed for Pakistani gas pressure and fuel quality
• One team for design, installation, commissioning and service
• Fast response from local engineers, without waiting on overseas suppliers
• Clear advice on fuel cost, including biomass options for the future

Safety and Controls

Gas and oil fired boilers need reliable burner controls. We supply burners with flame safety, automatic start and stop, low water cut-off and pressure controls, and we test every safety device at commissioning. You can read about the basic types of industrial boilers to understand how each design works.

Installation and Service

Our team handles delivery, installation, burner tuning, commissioning and operator training. After start-up we offer 24/7 breakdown support, yearly overhauls and genuine boiler spare parts from local stock.

Frequently Asked Questions

Which is cheaper to run, gas or biomass?
In most cases biomass costs less per ton of steam, but gas needs less space and handling. We can compare both for your plant.

Can gas and oil fired boilers be converted to biomass?
Some designs can be converted with a new furnace and fuel feeding. Our engineers will inspect your boiler and advise honestly.

What sizes of gas and oil fired boilers do you make?
We make them from 3 to 25 TPH, in fire tube and water tube designs, matched to your steam load and pressure.

Gas and Oil Fired Boilers Buying Guide for Pakistani Factories

Gas and oil fired boilers are the cleanest and simplest way to make steam. There is no fuel yard, no ash and very little smoke. That is why many food, pharma, dairy and beverage plants in Pakistan still choose them. But fuel prices and gas supply change from year to year, so it is important to buy a boiler that is efficient and flexible.

This short guide explains the main points to check before you buy, so you can compare offers with confidence.

1. Choose the Right Fuel Setup

Most gas and oil fired boilers use one of three setups:

• Natural gas only: the cleanest option where pipeline gas or RLNG is available.
• Light or heavy oil only: useful where gas is not available. Heavy oil needs heating and filtering before it reaches the burner.
• Dual fuel: a burner that runs on gas and switches to oil when gas pressure drops. This protects your production from gas load-shedding.

For many factories in Punjab, a dual fuel burner is the safest choice because it keeps steam running even when gas supply is cut in winter.

2. Fire Tube or Water Tube?

For small and medium loads, a wet back or dry back fire tube boiler is simple, compact and easy to maintain. For larger loads or higher pressure, an A-type, D-type or O-type water tube boiler is the better option. Read more on our fire tube boiler and water tube boiler pages.

3. Size the Boiler Correctly

Boiler size is measured in TPH (tons of steam per hour). Add up the steam used by all your machines, add a margin for future growth, and check your working pressure. AGK gas and oil fired boilers are available from 3 TPH up to 25 TPH. Our engineers can visit your plant and do a simple load study for you.

4. Look at Running Cost, Not Only Price

The boiler price is paid once, but fuel is paid every day. A small saving in fuel can be worth more than a lower purchase price. Ask about the economizer, burner control and insulation, as these decide how much fuel your boiler uses.

Ways to Cut Fuel Cost on Gas and Oil Fired Boilers

• Add an economizer: it uses hot flue gas to pre-heat feed water.
• Return condensate: hot condensate saves fuel and water treatment chemicals.
• Tune the burner: correct air-to-fuel ratio reduces wasted heat.
• Fix steam leaks and traps: small leaks waste a lot of fuel over a year.
• Insulate pipes and valves: bare pipes lose heat all day.

Our boiler services team can check your existing boiler house and show you where fuel is being lost.

Should You Switch from Gas to Biomass?

Gas supply to industry in Pakistan is not always stable, and the cost keeps rising. If your plant uses a lot of steam, a biomass boiler running on rice husk or wood chips can lower your cost per ton of steam. Many factories keep their gas and oil fired boilers as a standby and run a biomass boiler for the main load. If you do not want to invest in a new boiler, our biomass steam supply service is another option.

Safety Features on Our Gas and Oil Fired Boilers

• Flame failure protection and automatic burner shut-off
• Low water level alarms and cut-offs
• Pressure switches and safety valves
• Gas train with leak test and pressure regulators
• Operator training at the time of commissioning

Gas and Oil Fired Boilers FAQs

Which is cheaper in Pakistan, gas or oil?

It depends on current prices and the gas tariff for your industry. In most cases gas is cheaper than oil when it is available. Biomass is usually cheaper than both.

Can I convert my oil boiler to gas?

In many cases, yes. The burner and fuel train are changed and the boiler is tuned for the new fuel. Our boiler engineering services team can check your boiler first.

Do you supply spare parts for gas and oil fired boilers?

Yes. Burners parts, gauges, valves, pumps and controls are available through our boiler spare parts service.
