In addition if the product form is welded tube or pipe a joint efficiency factor of 0.85 is typically applied. This can be seen by several of the notes in the stress tables. For yield strength the safety factor in most cases is a multiplier with the joint efficiency factor of 0.85 applied in the same case as for tensile; in some cases a higher value of 90% yield may be used instead of the value.Get a Quote

The thermal efficiency of a boiler is the ratio of usual energy output to the energy input. By far the greatest component of the latter is the energy in the fuel; that supplied as power to the auxiliaries being negligible in comparison. BS 845: 1987 and USA Standard is ASME PTC-4-1 Power Test Code Steam Generating Units.Get a Quote
6.6.1 Efficiency. Boiler efficiency can be calculated using ASME Performance Test Codes (PTC). PTC 34 is used for waste combustors with energy recovery using the boiler as a calorimeter. Using this method the heat outputs losses and credits must be calculated. Heat credits correct the efficiency to standard ambient conditions such as air temperature.Get a Quote
https:// . 2. Indirect method: Indirect efficiency is also known as heat loss efficiency calculation method. In this method efficiency calculation is done by subtracting heat loss fraction from 100. Standard is ASME PTC-4-1 isused for calculating boiler efficiency by indirect method. The standards do not include blow down loss in the efficiency determinationGet a Quote
