Boiler Ratings - Spirax Sarco | First for Steam Solutions

This tutorial explains the three most commonly used boiler ratings: The 'From and at' rating for evaporation, the kW rating for heat output, and boiler horsepower. 'From and at' rating The ‘from and at’ rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the

Condensing water heaters Archives - A.O. Smith

Convinced of the enormous added value of condensing water heaters, A.O. Smith has been delivering condensing hot water solutions for many years now. By using the heat which is released in the process of burning gas for heating the water supply, almost all of the consumed energy can be applied in this process. This heat is transferred to the water via the heat exchanger. This is the basic

Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

how much resistance should a hot water heater element have

How Much Resistance Should a Hot Water Heater Element Have

In order to find the resistance of the heater element from the above described section, we must algebraically modify the formula to read (r = v/a). Since we know that the hot water electrical circuit feeds 220 VAC to the 16 ampere heating element the resistance of that element is equal to 13.75 ohms. We can round that number up to 14 ohms.

Dry saturated steam at 3 bar g is used to heat water flowing at a constant rate of 1.5 l/s from 10°C to 60°C. hfg at 3 bar g is 2 133.4 kJ/kg, and the specific heat of water is 4.19 kJ/kg °C. Determine the steam flowrate from Equation 2.6.7: As 1 litre of water has a mass of 1 kg, the mass flowrate = 1.5 kg/s
