Steam Calculators: Boiler Calculator

Mar 17, 2015 · 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.

Boiler Piping Flow Pipe Sizing Quality HVAC Heating 101

Boiler Piping Flow, Pipe Efficiency, and Proper Sizing Boiler Piping Flow Pipe Sizing. Typically these issues occur when the pipe is over-sized/under-sized or the pump selection is incorrect and provides the incorrect velocity for the system. A good example of this is as follows. Two brand new boilers were installed in the basement.

Boilers - University of Alabama

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Exhaust Draft Control | CleanBoiler.org

Dec 17, 2019 · Reasons for Increasing Exhaust Gas Temperature of Boiler. December 17, 2019. The heat loss of exhaust gas is the biggest one of all the heat losses of the boiler. Generally, the lost heat is 6% of the heat input into the boiler furnace. The heat loss of exhaust gas increases by 0.5% when the temperature of exhaust gas increases by 12-15%.

How to calculate the gas consumption of the gas boilers

Sep 12, 2019 · According to the actual situation of the boiler, the calculation is carried out. Then, the gas volume required for the operating hours of a 1 ton natural gas boiler = 0.7 MW * 3600 s / 36.22 MJ / Nm3 / 92% = 75 m3 / h. Note: The actual power of the boiler is generally not equal to the rated power, so the consumption of gas is only a rough estimate.

Exhaust fan in boiler room. — Heating Help: The Wall

When the boilers are running, it exhausts out the flue and has to pull extra air in from outside the box for combustion. When you run the fan, the fan is competing with the boiler for the makeup air and also for the chimney to actually be able to vent outside when the exhaust fan is trying to pull it back down.

Options for Improving the Efficiency of Heat Recovery

The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a

Exhaust Draft Control | CleanBoiler.org

Exhaust Draft Control Introduction. Boilers must maintain a proper flue draft for efficient combustion; too little draft can result in condensation, CO formation, flue gas spillage, and soot formation. Too much draft results in lost thermal energy from the boiler and higher electrical usage by the vent fan.

Boiler Flues - Ultimate Guide with Boiler Flue Regulations

Nov 05, 2019 · Boiler flues are fitted when using combi, regular, and system boilers. The only exception that may apply to a small number of homeowners is a back boiler. This is a type of boiler that is fitted behind a fireplace. If you have a gas boiler behind your fire, the emissions will exit through your chimney, rather than via a boiler flue.
