afbc boiler coal consumption

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

How do you calculate coal consumption in afbc boiler - Answers

How do you calculate coal consumption in afbc NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.


boiler and this paper also gives the description of calculation of efficiency for FBC boiler. Here calculation has been done for the 100TPH FBC boiler used in the Prakash Industries AFBC type using Indian lignite coal having a different chemical composition and properties.

Fluidized bed combustion - Wikipedia

FBC has a lower combustion temperature of 750 °C whereas an ordinary boiler operates at 850 °C. FBC has low sintering process (melting of Ash). Lower production of NO x due to lower temperature. Lower production of SO x due to capture by limestone.

How to Calculate the Coal Quantity Used in a Power Plant

The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.

Difference Between AFBC And CFBC Boilers--ZBG

CFBC boilers can be operated efficiently with a variety of fuels that include low quality coal, lignites, anthracite, coal blends, bagasse in sugar plants, wood residue and so on. These fuels are characterized by a high ash or moisture content, low heating value, and low volatile content and thus have lower costs.

how much kg coal consumed to 1 ton steam generation in afbc

Sep 11, 2017 · 1 kg of coal produces how much steam | AFBC Boiler.know the quantity of steam how much kg coal consumed to 1 ton 1, Boiler Steam Generation per hour, Kg many steam produce 1 tonne steam boiler.

AFBC Boiler VS CFBC Boiler

Atmospheric fluidised bed combustion boilers - AFBC boilers. Atmospheric fluidised-bed combustion (AFBC) boilers offer efficient, cost effective and reliable steam generation.AFBC technology promises to provide a viable alternative to conventional coal-fired boilers and other solid fuel-fired boilers.

How much coal is required to generate 1 TPH of steam in

However this data is based entirely on coal’s calorific value. Sometimes steam flow is about 1700 TPH at 460 TPH of coal and sometimes steam flow is about 1800 TPH at 400 TPH of coal. At design CV (3500) of coal 600 Mw boiler produces 4.3735 TPH of steam / unit TPH of coal.

AFBC ( Atmospheric Fluidized Bed Combustion ) BOILER COLD

Sep 02, 2017 · Inert fluidized bed is heated to the ignition temperature of fuel and fuel is supplied continuously into the bed. The fuel burn rapidly and the bed attain a uniform temperature. In afbc boiler combustion is take place at about 850- 950 degree Celsius. In this article we discussed about the afbc boiler cold start up and what the precautions are take before start up the afbc boiler light up ?
