Energy Performance Assessment of CFBC Boiler - ijert.o

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

Boilers Efficiency Calculation Indirect Meth

asme boiler efficiency calculations - Hot Water Boilers. how to calculate ASME boiler efficiency -ZBG Boiler. Calculating boiler energy losses. Boiler efficiency includes two calculation methods: Input-output (direct) Heat loss (indirect) With the input-output method, you calculate efficiency by dividing the boiler's Btu output by its Btu input and then multiplying this figure by 100.

Modelling of indirect steam gasification in circulatin

The indirect steam gasification in circulating fluidized bed reactors was studied by modelling. The object of study was a coupled 12 MW th gasifier-combustor system, which was fired by woody biomass. The heat for the steam-blown gasifier was produced in the air-blown combustor and transported by circulating solids between the interconnected reactors.

Indirect Fired Heaters | Pirobl

An indirect Fired Heaters can be understood as a boiler. The energy produced by the combustion of liquid or gas fuels in the boiler, is transferred to a heat-transmitting intermediate fluid – basically water in liquid or gas form or thermal fluids, which is responsible for transporting the energy to other equipment – reactors, exchangers, etc. – to feed the productive process.

Direct Steam Injection vs Indirect Steam Injection

2012-11-26 · In a direct steam injection process you exploit not only the latent heat, but also part of the sensible heat of condensed steam, whilst in an indirect process you trap and discharge hot condensate. Moreover in an indirect process you introduce further thermal

What is the Difference Between Direct and Indirec

Generally, direct fired heaters are used on construction sites, outdoor applications, or warehouses. On the other hand, a work space that is tightly sealed and lacks a working heating system is an ideal setting for a indirect heater. At Priority Rental, we offer a broad variety of direct and indirect
