How to calculte boiler heating sarface
You need to be a bit more specific in your question. You state you have 1 AC system but 2 thermostats. What type of heating system do you have? Gas furnace, Boiler, Electric heat, Hot Water? Is your heating unit separate from your cooling unit?
Surface Area (Sphere_ = 4 X pi X r^(2) = 4pi r(2) Volume (sphere) = (4/3)pi r^)3)
how do you calculate the rate of osmosis
HVAC Load Calculation is a formula used by a contractor salesmen that determines the proper tonnage size of heating and cooling systems to be installed in Residential or Commercial applications. The formula is used to calculate the total cooling and heating BTU'S (British Thermal Units) for the proper values of determining the correct tonnage to be installed in HVAC applications. Tonnage is the size of the HVAC system. Without this Load calculation the wrong tonnage could be installed and it causing to much humidity in the summer in cooling season and not enough heating in the winter season. Also the HVAC system may never stop running to reach the proper temperature that the thermostat is set for. Thus causing high electricity out of pocket cost.
yes.
Please be more specific...
The heating surface of a boiler is all the surfaces that have boiler water on one side and hot gases of combustion on the other. The surface in contact with the water is the surface that is measured.
hi i am kashif iqbal, u asekd that how can we calculate the capacity of biler through heating surface its a very simple for example a boiler having heating surface of = 1425 sq ft applying thumb rule = 1425/260=5.48 tons
This question is meaningless. Please be more precise.
Using a metal detector.
In fire tube boilers, normally the heat transfer area of reference is taken as the outside surface of the tubes. So you use the outside diameter of the tubes for the calculation of the heat transfer area.
for 1st class boiler attendent heating surface more than 1500 sq/ft .
Generally, the heat transfer area of reference is considered to be the outside surface area of the tube. Therefore, figure the outside diameter of the tube to get the heat transfer area.
The heat transferred from flames to a boiler depends on several factors such as the temperature of the flames, the surface area of the boiler, and the efficiency of heat transfer. In general, the heat transfer occurs through convection and radiation, with the flames heating the boiler's surface which then heats the water inside.
He = ASME = heating
To turn on the boiler for heating in the house, locate the boiler's power switch and turn it on. Adjust the thermostat to the desired temperature for heating. Wait for the boiler to heat up and start circulating hot water or steam through the heating system.
3.14*3*20*12= 2260.8 sq inthe heating surface of a fire tube boiler is determined by adding all of the surface of the tubes that have hot water on one side and/or fire or gases of combustion on the other, including the super heater and economizer.
