Calculation Details. Step 1: Determine Properties of Steam Produced. 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

Cost of fuel per kg or m³: Enthalpy of steam: kJ/kg. Enthalpy of water: kJ/kg. Fuel consumption for generating 1 ton of steam: kg = m³. Steam cost per ton in local

The reactor I am talking about is 600 m away from the boiler and receives steam of 1.5 Kg/cm2 may be due to pressure drop along the line. I do not know at what flow rate does this steam come. Steam enters the reactor jacket and leaves it as condensate. Now I have already calculated that I need 1.3 ton of steam to

BOILER EFFICIENCY IN STANDARD UNITS. * 1 BHP = 34.5 lbs steam/hr. * 1 BHP = 33,472 Btu/hr. * 1 BHP = 139.5 sq.ft. E.D.R. (steam). * 1 Sq.Ft. E.D.R. (steam) = 240 Btu/hr. * 1 Sq.Ft. E.D.R. (hot water) = 150 Btu/hr. * 1 Lb. steam (from and @ 212 °F) = 970 Btu/hr. * 1 Therm = 100,000 Btu

The real question: is condensate returned to the boiler? If not, you keep processing new water to steam, and 15000 kg/h of steam requires 15000 kg/h of new water (plus additional to offset any steam losses along the way) 15000 kg of water is about 15000 L (true at 4 °C, reasonable approximation from 1

Cost of steam. Example 5.1. Let us take a 5TPH (tons per hour) oilfired boiler, @10.5 kg/cm2g, using DM water at an ambient temperature of 30°C. Direct cost. First, we calculate the Direct costs of. •. Fuel. •. Water. •. Water treatment. •. Electricity. Fuel. = = 7945.66 Rs/hr. Assume the boiler operates for 24 hours a day for 335

Jan 31, 2013 – Hg = enthalpy of steam, in Btu/lb. hf = enthalpy of boiler feedwater in Btu/lb. ηB = true boiler efficiency (per ASME PTC 4.1 method) 1,000 = cost measured in units of 1,000 lbs. per hour. In this simplified calculation method, the formula assumes that one boiler is being used, one fuel and a single steam

1. 2, AML FBC Project: Steam cost analysis for Additionality. 3, BASE. 4, Description, UOM, Steam cost with DOC, Steam cost with SD, Steam cost with FO, Steam cost with Lignite, Steam . 15, 8, Fuel consumption rate, Tonne/hr or SCM/hr, 0.887, 2.148, 2.299, Calculated on the basis of heat input and NCV of individual fuel.

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg – hf) m (1). where.

(1 kw hr) … i want to know how much steam is produced at 220 kg/hr coal and 1320 lit/hr … How much coal is required to generate 1 ton of steam – Answers.com As a rule of
Boiler Fuel Consumption Calculation–ZBG
Jul 4, 2017 – For example, The calculation formula of fuel demand for steam boiler(saturated steam boilers) is as follows: Bj=B (1q4/100) Bj calculation of fuel consumption, kg/h. B fuel consumption, kg/h q4 boiler mechanical incomplete combustion loss,%. B=100Q/ (Qdw*) B fuel consumption, kg/h. Q effective heat

Calculating the amount of steam in nonflow batch and continuous flow heating processes. The time required to heat 75 kg of water (cp = 4.2 kJ/kgoC) from temperature 20oC to 75oC with steam produced from a boiler with capacity 200 kW (kJ/s) can be calculated by q = (4.19 kJ/kg.oC) ((60 oC) – (10 oC)) (3 l/s) (1 kg/l).

H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%. This method involves finding out the magnitudes of all the

I have a NAT GAS 26,500lb/Hr Steam boiler operating at 150psi. Boiler is used for a process variable load. My question is 1. Presently I am using 90,000 liters of feed water to create Putting your boiler data in SI units, this gives me a boiler steam output of 12.031 kg/h, or roughly 12 ton/h at 10,5 bar.

various pressure and valve size in most common use: • 1 kg / cm2 = 14.2 PSIG. GarwareWai Case Study: Boiler capacity. = 2.5 TPH. Steam Pressure. = 9.5 kg/cm2. Blowdown valve diameter = 1 inch. Holdup volume. = 5 m3. Feed water TDS. = 300 ppm (max.) Existing Boiler water TDS = 6000 ppm. As per formula:.
Gasworks: Calculating the True Cost of Steam – Questline
Boiler efficiency is defined as the energy in the steam produced by the boiler divided by the energy supplied from the fuel. The term kilograms of steam is the mass of water converted from the liquid to gas phase. This varies with temperature, but is about 1 kilogram per litre at room temperature. In general, it takes 4.19

Jun 26, 2017 – If your boiler supplies 400 pounds of steam per hour, for example, you would multiply 400 pounds by 1,194 to arrive at a figure of 477,600 BTUs. From there you'd need to calculate how best to distribute that heating potential throughout your structure, which involves a different set of calculations.
