  • Boiler Ratings and Boiler Load - Alken-Murray

    Boiler load - The horsepower, lbs of steam per hour, or BTU is the rating indicating the maximum capacity of a boiler. When a boiler operates at its maximum rated capacity, it is referred to as maximum load. If the load varies from hour to hour, it operates at a varying load.Load and load variations can influence the amount of chemicals required for treatment and the treatment controls required.Learn More

  • Commercial Combi Boilers - 4kW to 100kW - Natural Gas or

    Excellent efficiency – These commercial combi boilers are up to 109% efficient, when working on a 30% heating load at 30 Degrees C (typically an underfloor heating system), and are up to 98% efficient at the minimum load when being used on an 80/60 Degrees C heating system (typically an older radiator designed system). Heating a larger home Learn More

  • What is boiler modulation and boiler cycling? - HeatGeek

    Nov 01, 2018 · The wider the gap between the load and the minimum output of the boiler, the more the boiler will 'cycle' and run times reduced. Extreme cases of oversizing result in the boiler 'rapid cycling', although this can be also caused by a lack of flow round the system or scaling of the boiler.Learn More

  • Modulating Condensing Boilers - Madison Gas and Electric

    Modulating condensing boilers (mod-con boilers) can increase combustion efficiency to about 96%, up from the 80% efficiency of non-condensing boilers. They provide a range of firing rates to match the variable heating load of the building. However, mod-con boiler efficiency depends on the temperature of the water returning to the boiler.Learn More

  • Boiler Rental - Powerhouse Boiler Equipment

    This calculation translates the steam load (in pounds per hour) to boiler horsepower. Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5.Learn More

  • Turndown ratio - Wikipedia

    Turndown ratio refers to the width of the operational range of a device, and is defined as the ratio of the maximum capacity to minimum capacity. For example, a device with a maximum output of 10 units and a minimum output of 2 units has a turndown ratio of 5. The term is commonly used with measurement devices and combustion plant like boilers and gasifiersLearn More
