What Is Your Diesel Steam Boiler Consumption Per Hour?

Diesel consumption calculation

• Diesel steam boiler
  Oil consumption per hour = hourly gas production of oil steam boiler × (heat of oil steam – heat of feed water) / low heat value of fuel oil × thermal efficiency of the boiler.
•  Diesel hot water boiler 

operating 1-hour oil consumption = water weight(Kg) × specific heat capacity of water × temperature difference (inlet and outlet water temperature difference) / fuel oil heating value × boiler thermal efficiency

The above two are more specific ways, but in fact, we can use the unified formula to make a rough estimate, and then the boiler manufacturer’s engineer will accurately calculate it after the parameters of the boiler are determined.

Diesel steam boiler oil consumption per hour general formula:

1ton diesel steam boiler consumption= 3600 * heat power / diesel calorific value / boiler efficiency

Take a 5 ton steam boiler as an example, its thermal power is 3.5MW, assuming that the diesel calorific value is 42Mj/kg and your diesel steam boiler fuel efficiency is 95%, it can be concluded that a 5 ton boiler needs to consume oil per hour = 3600*3.5/42/0.95, which is about 315.789kg.

Different capacity diesel fired steam boiler fuel consumption(base and supposed as above calculate)

1 ton diesel steam boiler=consumption 65kg. As this, If you have a how many tons of boiler, you just multiply the tonnage by 65kg, then you could get your diesel fired steam boiler one-hour fuel consumption data.

As we are the direct diesel steam boiler manufacturer, we could supply you with the best 1 ton steam boiler price

Following is some data that we make for your quick reference.

• 1t skid-mounted oil boiler requires 63kg of oil consumption per hour
• 2t small oil boiler requires 126kg of oil per hour
• 3t horizontal oil boiler requires 189kg of oil per hour
• 4t oil-fired boiler requires 252kg of oil per hour
• 5t oil-fired boiler requires 315kg of oil per hour
• 6t oil-fired boiler requires 873kg of oil consumption per hour
• 8t condensing oil boiler requires oil consumption 504kg per hour
• 10t packaged oil-fired boiler oil consumption 630kg per hour
• 12t oil-fired boiler 1 hour oil consumption 756kg
• 15 tons oil furnace requires 945kg of fuel per hour
• 20 tons oil-fired boiler requires 1260kg of fuel per hour
• 25 tons of oil-fired steam boiler requires 1575kg of fuel per hour
• 30 tons of oil-fired boilers consume 1890kg of oil per hour
• 40 tons of oil-fired boilers cost 2520kg of oil per hour

• 60 tons condensing oil boiler requires 8730kg of oil per hour

How Does Your Diesel Boiler Efficiency?

Diesel steam boiler’s Light Diesel combustion characteristics

Diesel fuel is a liquid fuel, its boiling point is always lower than the ignition point, so the combustion of fuel oil is always in the gaseous state.

After diesel fuel is sprayed into the furnace chamber by atomized oil particles, it is heated by the high-temperature flue gas in the furnace and gasified, and the gasified oil gas meets the oxygen in the surrounding air to form a flame.

A part of the heat generated by combustion is transferred to the oil particles so that the oil particles continue to gasify and burn until the combustion. The smaller the diameter of the oil grain, the faster the oil grain burns.

Similarly, the oxygen required for oil grain combustion can be supplied in time, the faster the oil grain combustion.

Therefore, to improve the combustion efficiency of diesel steam boiler, the following points must be achieved:

1) Improve the quality of atomization, reduce the diameter of oil particles;

2) Increase the relative speed of air and oil particles;

3) Reasonable air distribution.

Diesel Steam Boiler High efficiency

• Yongxing’s Diesel steam boiler with FGR low nitrogen design saves 35% energy compared to traditional boilers

FGR flue gas recirculation technology (NOx＜30mg/m3)

We adopt the German technology “kemen” ultra-low nitrogen gas burner, together with the flue gas recirculation (FGR) technology, about 10%~30% of the flue gas (temperature about 170℃) at the end of the boiler is sucked into the burner inlet through the flue gas duct, mixed with combustion air and then enters the furnace.

Thus, the temperature of the combustion area is reduced, and the concentration of oxygen in the combustion area is reduced at the same time, which ultimately reduces the generation of thermal NOx and achieves the NOx emission of less than 30mg/m3 in the tail flue gas of the boiler.

• Our diesel fired steam boiler condensing machine helps you to save heat 10~15%.

Conventional boilers emit high-temperature flue gas directly to the atmosphere, which results in a significant waste of heat.

To increase heating efficiency, we retrofit the condenser at the flue gas outlet, where the cold water in the condenser is heated and later returned to the boiler interior.

The diesel steam boiler inlet water temperature is increased, protecting the boiler casing and reducing the heat demand, so your fuel costs are reduced. This is our ultimate aim to increase efficiency.

• Improving the diesel steam boiler combustion rate

To improve your boiler combustion efficiency, we promote fuel combustion in the boiler furnace regularly as follows.

1. Air supply and air volume.

A reasonable air supply, according to the different performance characteristics of the boiler combustion process, controls the adjustment of air supply.

2. Air coefficient.

The boiler chamber air is reasonable also affects the combustion rate, such as excess air coefficient will cause the chamber temperature to reduce the combustion rate, and for other fuel, boilers will also produce more black smoke, in addition, if the excess air coefficient is too low, it will lead to incomplete combustion of fuel.

3. High furnace chamber temperature.

High furnace chamber temperature is a necessary condition for the rapid combustion of fuel.

4. Operating load. This should be set under the boiler instructions and should not be allowed to run at too low or excessive a load.

• Compare Diesel Steam Boiler Overall Design And Use

The same material of condenser and energy saver, the different energy-saving design will also affect the service life of the boiler.

For example, whether diesel steam boiler is 2 return, 3 return or 4 return; whether the condenser separates primary water from system water, protection measures in case of boiler shutdown, protection measures against freezing and water shortage in the heating season, etc.

Diesel steam boiler operation, the user’s use of the way will also affect the service life of the boiler.

• Choose A Better Water Softening System

If your water quality is too hard or bad, but without any treatment, it will bring great harm to diesel steam boiler operation.

① Hard water is heated and evaporated in the boiler, which not only provides chemical reaction conditions for impurities in the water but also makes the pot water continuously concentrated and forms limescale. The thermal conductivity of scale is tens to hundreds of times smaller than the thermal conductivity of steel.

Therefore, when the boiler has scale, the heat transfer performance of the heating surface becomes poor, the thermal efficiency becomes low, wasting fuel, damaging the heating surface, reducing the boiler output, the scale will reduce the service life of the boiler.

② Corrosion of boiler water-cooled wall, convection tube bundle and pot barrel, and other components will be caused by poor water quality and corrosion.

Seriously, it directly affects the safe operation of your diesel steam boiler, shortening the service life of the boiler and causing economic losses.

③ Steam and water together, easy to produce water hammer effect, easy to cause damage to the steam system connections; cause steam valves, return elbow parts and superheater corrosion inside.

Therefore, before using the boiler, analyze the local water quality in advance and submit the report to our boiler plant, and we will choose a reasonable water softening treatment equipment according to the softness and hardness of the water.

After diesel steam boiler’s water treatment equipment will be certain filtering, decomposition and other technical treatment of water to eliminate impurities so that it is purified.

Help you achieve to reduce boiler scaling, corrosion and vapor co-temperature, and other undesirable phenomena, extend the service life of the boiler, save fuel, to ensure the safe and economic operation of the boiler.

The water treatment we are talking about is external water treatment and internal water treatment. Our boiler factory is generally equipped with external water treatment for you.
