How much energy does it take to produce 1kg of steam?

Heat requried for making saturated steam at 100c = latent heat of vaporization= 2260000J. By this calculation we need around 80g of coal or 60g of coal to produce 1kg of steam from water at 25 c.

How is steam production calculated?

Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. This is an average industrial boiler.

How do I calculate steam boiler production?

Calculation Details

1. Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate.
2. Steam Mass Flow = Feedwater Mass Flow – Blowdown Mass Flow.
3. Steam Mass Flow = Feedwater Mass Flow – Feedwater Mass Flow * Blowdown Rate.
4. Feedwater Mass Flow = Steam Mass Flow / [ 1 – Blowdown Rate ]

How much steam can 1 kg of coal produce?

Approximately 8 kg of steam can be produced from burning 1 kg of coal.

How do you find the mass of steam?

$Q=mL$ where Q is the heat energy absorbed per mass m and L is the latent heat of the material. $Q=mc\Delta T$ where Q is the heat energy absorbed per mass m, c is the specific heat of the material and $\Delta T$ is the change in material. Hence, the required mass of steam is 30g.

When 1 kg of water is boiled What mass of steam is made?

So, boiling a kilogram of water generates a kilogram plus about ten nanogram of steam.

How do you calculate fuel consumption of a steam boiler?

The calorific value of the fuel is calculated according to 35.53 MJ/Nm3, then the gas consumption of the 10 ton boiler hour = 7MW*3600s/35.53MJ/Nm3/90\%=788m3/h, If the calculation is carried out for 8 hours per day, then the 10 ton gas fired boiler consumes 6304 cubic meters of natural gas per day.

How do I calculate steam boiler capacity?

Boiler Capacity – Engineering ToolBoxA boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg – hf) m (1).

How is boiler TPH calculated?

What is the capacity of a boiler if its heating surface area is equal to Assume boiler with dimensions 10 x 10 x 20 surface is 10 x 10 x 2 = 200 and 10 x 20 x 4 = 800 total 1000 SM volume is 10 x 10 x 20 = 2000 M^3. Boiler shall give you 25 TPH for a Agro-waste fired Saturated Steam Boiler.

How do you convert steam pressure kg cm2 into steam flow rate kg HR?

By the discharge pressure get the specific volume of steam via steam table. Divide the volumetric flowrate(m3/hr) by specific volume(m3/kg) to get mass flowrate(kg/hr).

How do I calculate the energy flow of steam?

Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Steam Energy Flow = Specific Enthalpy * Mass Flow

How much water does it take to produce 1kg of steam?

Ice, water and steam (gas) are the three different phases of one single substance viz. H2O. So the amount of water required to produce 1 kg of steam is the same that is 1 kg of water. This is also applicable to the ice-watet or ice-steam.

How do you calculate the specific enthalpy of steam?

The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = 799.9 psig Temperature = 488.7 °C [Steam Property Calculator] => Specific Enthalpy = 1,462.0 btu/lbm

What is the steam property calculator and how does it work?

Determines the amount of fuel energy required to produce steam with specified properties at a given flow rate using general boiler operational characteristics. Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality).
