Consumption of diesel heating boiler - method of calculation

Diesel heating boilers - the second most popular after the gas boilers.They have a number of advantages, among which the possibility of full automation, which makes them considerably more popular solid, and cost in comparison with electric boilers.

Diesel boilers require that arrangement a separate room, as well as fuel storage tank to ensure long-term trouble-free operation of the boiler.To choose the right amount of capacity, as well as to find out the amount of fuel needed to heat your home during the season, requires calculation of diesel fuel heating boiler.

  • Area of ​​heated premises of the house;
  • The heat output of the boiler;
  • number of days in the year when the boiler will run at maximum load (depending on the region);
  • boiler load in the remaining months.

Calculation of fuel for heating boiler

calculated based on the area of ​​the house.It is considered that for heating the building, which was built with the implementation of building codes, is required 1 kW of thermal power to 10 m2

.

The calculation formula of power heating boiler

power heating boiler calculation formula

mass of diesel fuel needed for one hour of operation of the boiler, can be roughly determined by multiplying the boiler output by a factor of 0.1.

The formula for calculating the time fuel consumption

formula for calculating the hourly consumption of fuel

number of hours of operation of the boiler at full load can be determined by multiplying the number of cold days in the year 24.

The formula for calculating the amount of operation of the boiler at full load

formula for calculating the amount of the boiler at full load

Similarly, we cancalculate the number of hours the boiler with partial load, for example, for heating a two-planimetric boiler heating water.

total mass of fuel is calculated by multiplying the hours of work on an hourly rate.

If payment must be made in liters, for example, to calculate the volume of the container, you must use the following formula.

Calculation of storage volume

Calculation of

Example Calculation capacity: House of 90 m2, the number of days in the year when the boiler is operating at full capacity - 120, the boiler runs half the power for another 60 days.It is necessary to calculate the annual fuel consumption and the volume of container under the diesel fuel.

Calculation:

  1. boiler output is Pk = 90/10 = 9 kW.Choose a pot with a nominal capacity of 10 kW.
  2. All fuel consumption Mt = 10 × 0.1 = 1 kg / hour.
  3. number of hours of operation of the boiler at full load t1 = 120 x 24 = 4,800 hours.
  4. number of hours of operation of the boiler half the power is calculated from the operating time of 12 hours a day: t2 = 60 · 12 = 360 hours.
  5. total number of hours the boiler t1 + t2 = 5160 hours.
  6. total fuel consumption is Mt.obsch.· 1 = 5160 = 5160 kg = 5.16 t.
  7. Vt.obsch volume capacity.= (5.16 · 1000) / 0.84 = 6142 liters = 6,14 m3.

By receptacle under the diesel imposed certain requirements.It should be corrosion resistant, have ribs drain valve for removing the precipitate, the breathing valve and level gauge.Install a storage tank of diesel fuel in a separate room in compliance with all fire protection requirements.

Properly executed payment - a pledge of uninterrupted heating homes.These formulas are relevant for well insulated buildings with a ceiling height of three meters.If your home is built according to the original design, with high ceilings and large panoramic windows, you need to make a more accurate calculation of the power of the heating boiler.
