If your boiler supplies 400 pounds of steam per hour, for example, you would multiply 400 pounds by 1,194 to arrive at a figure of 477,600 BTUs. 0000012949 00000 n 0000001731 00000 n MBtu (million Btu) 1000. 0000009809 00000 n (Saturated Liquid). �z�Ȭ��[*����2^!���2�� ��O�gU �0�c�����w���7˿�2�v�hD^��.wZk�\� w=.���V�nqKc��� %PDF-1.3 %���� 0000001971 00000 n Steam, Boiler, and Blowdown Pressure are the same. 0000012346 00000 n Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. 0000001684 00000 n It is the total heat in steam above 32°F. The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Deaerator provides feedwater near the boiling temperature for the deaerator's set operating pressure. Water holds 180 BTUs at 212 then an additional 970.3 BTUs of latent heat to convert the water into steam. A boiler fired with natural gas costing $8.00/MMBtu produces 450-pounds-per-square-inch-gauge (psig) saturated steam and is supplied with 230°F feedwater. steam condensing rate is known. Specific Volume of Liquid (Column 7). 0000002891 00000 n Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. For the low-pressure steam typically used in heating systems, that ratio is 1,194 BTUs for every pound of steam the system provides. The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Using the Steam Property Calculator, properties are determined using Deaerator Pressure and Quality = 0 (Saturated Liquid).
