# relation between ton and kw for boiler

## Definitions of BTU BTUs & related HVACR TermsDefine B

Table of British Thermal Units BTU's Translated into Other Measurements: 1 BTU = One BTU = the amount of energy needed to raise 1 pound of water by one degree Fahrenheit or 1 o F. One BTU is equal to 252 calories, so by the definition of calorie, 1 BTU will raise 252 grams of water by one degree Centigrade or 1 o C.. One BTU is also described by some as about the amount of energy given by

## Boiler Capacity - Engineering ToolB

W = boiler capacity (Btu/h, kW) h g = enthalpy steam (Btu/lb, kJ/kg) h f = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s) Boiler Horsepower - BHP. The Boiler Horsepower (BHP) is. the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 o F, with feedwater at 0

## kW and kWh Explained - Understand & Convert Between Pow

The building used 41 kW (on average) across the whole of last week. The building used 19 kW (on average) across all the Saturdays and Sundays since March 2017. (We don't need to care how many Saturdays and Sundays there were since March 2017.) The building used 38 kW (on average) between 09:00 and 17:00 on Tuesday, December 25th, 2018.

## What do kW and kWh Mean? | Boiler Gui

Watts measure energy in relation to time so a boiler with a maximum output of 24kW will produce 24,000 joules of energy per second when in operation; this energy will heat water for your home. The higher the kW rating of a boiler, the more radiators and taps it can supply at one time.

## Why AC rated in Tons, Not in kW or kVA? - Electric

A Ton of refrigeration (RT) is a unit of power used to describe the heat-extraction capacity of air conditioning and refrigeration equipments. It is defined as the heat of fusion absorbed by melting 1 short ton of pure ice at 0 °C (32 °F) in 24 hours. How many kW and …

## Commonly Used HVAC Formulae and Conversio

1.0 Ton = 12 MBH = 12,000 Btuh 1.0 Therm = 100,000 Btuh = 100 MBH COP = 3.516 / (kw / Ton) EER = Tons x 12 / (Total kW input) Btuh = Watt x 3.412 HP = kW x 1.3405 1 Boiler HP = 33.48 MBH 1 US Gallon = 8.33lbs Latent heat of vaporization of steam in air (average) = 1,050

## Determining Boiler Capacity from Heating Surface Ar

Dec 10, 2004· I was once told that there is an equivalence between boiler capacity (steaming rate) and the heat exchange surface area. Does anyone know the relationship? I am talking about an older (1972 vintage) D-style watertube steam boiler with a design pressure of 250 psig. The nameplate states that the surface area is 3089 sq ft.

## Kilowatts to tons of refrigeration (RT) conversion calculat

Conversion Calculator · BTU/hr to Tons · BTU/hr to Kilowatts · Bhp to Kilowatts · Horsepower to Kilowatts 1 RT = 3.5168525 kW. One kilowatt is equal to 0.284345 refrigeration ton: 1 kW = 0.28434517 RT . So the power P in refrigeration tons (RT) is equal to the power P in kilowatts (kW) divided by 3.5168525: P (RT) = P (kW) / 3.5168525 . Example. Convert 5 kW to tons: P (RT) = 5 kW / 3.5168525 = 1.4217 RT. kW to tons conversion table

## What is the relation between kwh and kcal? - Quo

Nov 24, 2017· A kWh is an ISO measure of energy (ability to do work). 1 kilo Watt hour is 3600 kJ or kilo Joules, which is the basic measure of energy, and would raise an object of 1000kg through 360m in a gravity field of 10N (what we have here on earth). A ca

## Steam Calculators: Boiler Calculat

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.
