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. From there you'd need to calculate how best to distribute that heating potential throughout your structure, which involves a different set of calculations.

At Nationwide Boiler Inc., we have the largest utilized rental boiler fleet in the world. Our rental equipment consists of 47.5 hp to 1,000 hp mobile boiler rooms and 30,000 lb/hr to 125,000 lb/hr trailer-mounted watertube boilers in saturated and superheat steam conditions.

Steam Generation Benchmarking the fuel cost of steam generation, in dollars per 1,000 pounds ($/1,000 lb) of steam, is an effective way to assess the efficiency of your steam system. This cost is dependent upon fuel type, unit fuel cost, boiler efficiency, feedwater temperature, and steam pressure. This calculation provides a good first

Boiler feed units are generally sized for 5 minutes of net storage. You can feed your boiler for 5 to 10 minutes, depending on the load, to keep it steaming while waiting for condensate to come back. In smaller systems, up to 150,000 sq ft EDR, 5-minute pumping capacity is a good rule of thumb.

Other Useful Information: 1 SQ.FT. E.D.R. = 240 BTUH @215 ° F. 1 Boiler H.P. = 33493 BTU/Hr Where SpGr = Specific Gravity (Water is 1.0). Condensate Pump Sizing: . A: Pump Capacity = 2 x Actual GPM Condensate B: Minimum Receiver Size in Gallons = 1 minute x GPM found in part A C: Pump Head (In Feet) = Static Lift in Feet + Friction Losses in Feet + Pressure In Vessel That's Being

For instance, steam can be assumed to be 350 psia (pounds per square inch absolute), which has a temperature of 432 degrees Fahrenheit. This steam has a corresponding latent heat of 794 btu/lb. If the steam flow is 1,000 pounds per hour, then the total heat input per hour is 794,000 btu.

Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3 ) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.

Flow mass unit conversion between ton (metric)/hour and pound/hour, pound/hour to ton (metric)/hour conversion in batch, ton/h lb/h conversion chart

NOTE: Triad highly recommends that boiler feed water be treated before it enters the boiler. The water in the boiler should have a pH level of between 7.5 and 8.5, and in no case above 9.5. If feed water temperature is below 140°F it also requires an oxygen scavenger. See WATER in Section III of this boiler manual.

In order to ensure the safe operation of condensing 1 tonneh capacity waste heat boiler, condensing boilers must strengthen the monitoring of, and therefore should be installed pressure gauges, water level (water level alarm), safety valve, gas leak alarms, thermometers and other instructions and on the protection of condensing boilers condensing boiler safety accessories.

4.) maximum steam generating capacity in pounds of tonnes per hours.This term is the most informative and easiest to understand if it refers to steam properties the boiler is designed for. (Large boiler capacities are often given in lbs or tonnes of steam evaporated per hour under specified steam conditions, for smaller boilers capacity is

The capacity of the boiler was 530,000 lb/h (240 TPH). During that time I had been studying about the requirement and design calculations for boiler feed water (BFW) for the boiler since it was part of the overall design engineering.

The amount of steam required to produce 1 MW of electric power depends upon so many factor, the most important being, the steam temperature and pressure at the exit of Boiler, the isentropic efficiency of Turbine, the availability of reheat, the c

Buying or Renting Boilers: What a Boiler BTU Rating Should Mean to You. If you review any materials online or in print about industrial boilers, you'll notice that the capacity of most boilers is measured in horsepower or in BTUs. The greater the BTU of your equipment, the greater capacity your system has to create heat.

RE: Determining Boiler Capacity from Heating Surface Area chicopee (Mechanical) 5 Dec 04 19:27 Since Your D-type WT boiler has water-cooled metallic walls,the average heat release in the furnace is 30,000 btu/hr per cu.ft. of furnace volume for continuous operation and 60,000 for peak operation per Kent"Power" 12 th Ed. pg 7-75 table 3.

The real capacity will be 16,737,500 = / (1194.2 - 148) = 15.998 lb / hr The difference between the nominal capacity and the real capacity in this example appears to be low, but it is significant because it represents an increase of 8% of the capacity. If a boiler is over fired to its nominal capacity, the result will be a reduction in the

This will be 30 pounds multiplied by the factor of evaporation for 70 pounds gauge pressure and 100 degrees feed temperature, or 1.1494. 30 × 1.1494 = 34.482, or approximately 34.5 pounds. Hence, one boiler horse power is equal to an evaporation of 34.5 pounds of water per hour from and at 212 degrees Fahrenheit. The term boiler horse power

Boiler capacity = 2.5 TPH Steam Pressure = 9.5 kg/cm2 Blowdown valve diameter = 1 inch Holdup volume = 5 m3 Feed water TDS = 300 ppm (max.) Existing Boiler water TDS = 6000 ppm As per formula: Blowdown = 300 x 100 6000 - 300 = 5.263 For 2.5 TPH capacity boiler = 2.5 x 5.263 100 = 0.131 = 131 litres / hrs

C orrectly Sizing a Steam Boiler-What do I need to know?. The correct selection of a steam boiler output is critical to its operation, efficiency and performance. If undersized for the system load, then steam pressure will rapidly decrease thus causing the boiler to collapse its steam space, in turn causing low water alarms and ultimately burner lockout.

Designed for pulverized coal, B&W's advanced once-through ultra-supercritical boilers are usually applied to systems with a capacity of 400 MW or more. These clean and efficient boilers usually operate at throttle pressures of 3500 psi (24.1 MPa) or more and steam temperatures in the 1100F (595C) range.

For example, if we have a natural gas boiler with an input rating of 100,000 Btu/h and a heating capacity of 85,000, we would have a steady state efficiency of 85 per cent. This steady state can only be measured when the boiler is at full load and all the conditions, such as return water temperature, air temperature, air/fuel ration, and so on

confused the tech rep at the relief valve manufacturer of the one we used, also confused boiler tech rep. everyone says go by btu but when stamped 600 lb/hr on boiler I have no way to argue with the state inspector. watts tech rep (not the brand we used) finally said use the 970=1lb. we originally used a 510,00 relief on 500,000 input. changed to larger one now

how can we calculate boiler capacity?.. Answer / manoj kumar It is common to express the output of steam boilers in Boiler Horsepower, MBTU or in Pounds of Steam delivered per hour.

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.
