Reasons for Gaps Between Direct and Indirect Efficiency
This article tries to find out the reasons behind this wide gap between direct and indirect efficiency. First of all, we will have a look at both the methods of calculating boiler efficiency. Direct Efficiency. In the direct method, efficiency is calculated by dividing energy delivered by the boiler by energy input as fuel, using the equation:
Direct Steam Injection Solutions for the Energy and â€¦
Pick's compact size compared to indirect heat exchangers allows more flexibility in installation. Couple this with ease of maintenance and reliability and Pick Direct Steam Injection Heaters are clearly the water heating choice for the Energy & Power Industry.
2015-12-29 · The Direct Steam Injection Humidifier injects and disperses atmospheric or low pressure steam into a building's air supply system to attain and maintain the desired humidity level. It uses steam from an in-house boiler to humidify the air. The Direct Steam Injection Humidifier is controlled by an Electronic Steam Controller (SKDESC-J) that
The calculation of boiler's fuel efficiency boiler should consider the consumption amount of fuel used, so it is very appropriate to be used as a point of boiler economic analysis. Direct Method. There are two popular methods for calculating the fuel efficiency of the boiler; the direct method and the indirect one.
2019-10-20 · The following article will guide you about how to calculate boiler efficiency by indirect method. Definition of Boiler Efficiency: The boiler efficiency is defined as the ratio of heat actually used for producing steam in a certain period to the heat supplied in the furnace during the same period.
Boiler Efficiency By " boiler efficiency "is meant the measure of ability of a boiler or steam generator to transfer the heat given it by the furnace to the water and steam. There are two methods of determining boiler efficiency Indirect method Direct method In indirect method, the efficiency is calculated by determining the losses in the
2019-7-1 · 1) Direct method 2) Indirect method 1) The Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. This is also known as 'input-output method' due to the fact that it needs only the useful output (steam) and the heat input (i.e. fuel) for evaluating
How can we find enthalpy of boiler feed water? - Quora
Boiler Efficiency It is a well known fact that the initial cost of boiler is a small part of total costs associated with the boiler over its lifetime. In the operational life of a boiler, major costs arise out of the fuel costs. Ensuring efficient
