SNCR is a well-known technology for reduction of NOx from power boilers. Ammonia or urea is injected straight into the furnace or cyclone inlet and mixed with the hot flue gas. Ammonia reacts with nitrogen oxides to produce water and nitrogen. The reduction depends on the design and load of the boiler, but is normally in the range of 20 to 70%.
The main trend these days seems to be that fluid bed technology is used in most biomass boilers, with the simpler BFB for smaller installations and CFB for anything over 50 MW e. Leading suppliers  are offering commercial solutions for 300 MW e plant fired on biomass and supercritical plant up to 800 MW e for cofiring biomass with coal.

CFBC Boiler vs Pulverized Fired Boiler - SlideShare
CFB boilers and gasifiers, the superficial gas velocity is higher (~3–6 m/s), requiring cyclones to capture the entrained bed material for return to the boiler in order
2013/5/15 · The advantage of circulating fluidized bed (CFB) boilers in China is their ability to utilize low rank coal with low cost emission control. However, the new National Emission Regulation (NER) issued in early 2012 brings much more stringent challenges on the CFB industries, which also causes much attention from other countries. Based on the principle of a CFB boiler and previous operating

operation of a boiler for any purpose." Under the rule, [s]hutdown begins either when none of the steam from the boiler is used to generate electricity for sale over the grid or for any other purpose (including onsite use), or at the point of no fuel being fired in the

It has an advantage in regions with limited water resources. This flexible and economical technology can remove a wide range of pollutants such as SOx, Particulate Matter, Acid gas and Organic compound in flue gas from boiler.
The first lower energy consumption CFB boiler based on the re-specification of the fluidization state began commercial operational in 2007. As shown in Fig. 5, the field test results  showed that with the pressure drop decrease from 7.3 to 3.2 kPa, the solid suspension density in the dilute zone was barely influenced due to the higher collection efficiency of the cyclones.
Trained operators on CFB, PC Boiler and Aux Plant Operations. capacity of 3,800 TPD with storage capacity of 40,000 tons. Directed teams of up to 200 members in coal and petroleum fueled power and chemical production facilities for Operations and Maintenance. Set budgets for scheduled CFB boiler outages and turbine inspections.
representing over 4500 MIW Of plant capacity. The second is the circulating fluidized bed scrubber (CFBS), which circulates boiler ash and lime between a scrubber and a fabric filter. Amec Foster Wheeler has installed 78 CFB scrubber units representing over
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating the primary loop to the secondary loop, or a 3-way valve …
