## ﻿boiler Agent heat rate calculation ### Gas Vacuum Boiler Project

The deep matched technology of new combustion and heat transfer no longer sacrifices the boiler's key characteristics to adapt to the burner characteristics, making the gas boiler a complete thermal system with low nitrogen emissions. ### Electric Steam Boiler Project

The advantage of the electric heating steam boiler is that there is no combustion chamber and no chimney is needed, so the heat loss does not have to be considered, and the thermal efficiency can reach 98% or more. ### Gas Steam Boiler Project

This series of boilers adopts the design structure of full-membrane wall, and the sealing effect is very good. Multi-layer insulation materials are laid in the transmission pipeline and welding place to minimize the heat loss of the furnace body.

Jun 18, 2014 · For instance, if a boiler has an Input of 200,000 BTUH and a Gross Output of 160,000 BTUH, that boiler would be running at 80% combustion efficiency. It's not hard to figure this out. Just divide the big number into the little number and then multiply the result by 100 to get a percentage. And this brings us to Net Output.

Water heater Calculation: Water heater power P (kW) in kW is equal to the 4.2 times of the quantity of water L in Liters and the temperature difference divided by 3600. Hence, the required power to heat the different temperature formula can be written as, P (kW) = 4.2 x L x (T 2-T 1) / 3600. T 1 = Initial water temperature. T 2 = Final water temperature.. From the above formula, we can

A British Thermal Unit, or BTU is a unit of measurement of energy. 1 BTU is the energy needed to heat 1 pound of water by 1° Fahrenheit. We often refer to the British Thermal Unit as a BTU, but the rating is actually the BTUs per hour, or BTU/h. 1 BTU is the equivalent of 1,055 joules or .293 watts.
