desulphurisation rate of 85 in the cfbc boiler

The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.
Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.
Automatic production line.

The welding of important parts like the vertical and circular seams of the boiler, the tubes, the inside of boiler and the flange are all adopted automated welding processes such as submerged arc welding or gas shielded welding to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.
Tube flange weld adopts robot welding.
The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.

Besides the use of low sulphur fuel, the techniques that are considered to be BAT are mainly the wet scrubber (reduction rate 92 – 98 %), and the spray dry scrubber desulphurisation (reduction rate 85 – 92 %), which already has a market share of more than 90 %.

SPECIFIC INFLUENCE OF BIOMASS ON THE DESULPHURISATIO

limestone into the boiler furnace or on adding of ground limestone into coal. If we use the stechiometric rate CaCO 3: SO 2 at values 2-2,5 : 1, then typical achievable desulfurization is in the range of 85-90 % - dependent on sulfur content in coal and limestone reactivity [1- 3]. The following reactions are running

Pulverized combustion vs Circulating Fluidized Be

A boiler is equipment that is sold with guaranteed system efficiency. Some people call it design efficiency to distinguish it from the operational efficiency. For instance saying a boiler has a guaranteed efficiency of 90 % means 10 % of the energy input in the boiler (mostly fuel energy) is lost and is not used

desulphurisation eficacy may be achieved include bed temperature of approx. 850°C, oxidative atmosphere and the excess of sorbent Ca/S=2–4 (utilisation rate does not exceed 30%) [2]. In the luidised bed the SO 2 bonding occurs in accordance with formula (5). In order to improve desulphurisation eficacy, an

boiler CFB 135 MW – CFBC Boil

Circulating fluidized bed is a relatively new technology with the ability to achieve lower emission of pollutants. Extensive research has been conducted on this technology for the past 10 years because pollution in the world is getting more serious by the day and clean practice will be very crucial for the sustainability of the earth.

Design of CFBC Boiler | Fluidization | Bioma

CFBC requires huge mechanical cyclones to capture and recycle the large amount of bed material, which requires a tall boiler. A CFBC could be a good choice if the following conditions are met. • • • Capacity of boiler is large to medium.

Simultaneous Carbonation and Sulfation of CaO in Oxy-Fue

Techno-economic analysis of PC versus CFB combustio

desulphurisation could necessitate additional scrubbers for CFBC and negate this advantage. The potential benefits of CFBC have previously been offset by the greater specific capital cost of the boiler equipment, smaller unit size preventing economies of scale, and slightly lower efficiencies.
