The waste stream produced by this syngas scrubber is analogous to the wastewater produced in flue gas desulfurization (FGD) at a coal-fired power plant. This is to be expected since the gasifier is "burning" coal or some other fuel source and releasing the same types of contaminants produced in a coal-fired boiler.

Read MoreThis model suggest that E α( ) and A α( ) are a function of chemical reaction. It has two meaning: (1) Coal combustion characteristics are different under different burnout ratio; (2) The same degree of combustion reaction has the same chemical
Read MoreThese figures are based on using coal containing 3.36 percent sulfur and having a heat content of 11,700 Btu/lb. One spare scrubber was assumed for each boiler. Land was assumed to cost $5000 per acre. The heat rate was 9500 Btu/kWh. The capital costs
Read MoreIt includes an analysis of the availability of low-sulfur coal and of coal cleanable to compliance levels for alternate New Source Performance Stan- dards (NSPS). Various alternatives to physical coal cleaning (such as chemical coal cleaning, coal conversion, and

Read More1/11/2008 · Each scrubber was installed for each boiler of 300 MW unit. The two boilers were sub-critical natural circulation boiler. The maximum continuous rating of the boiler is 1025 t/h. The sulfur content of design coal rank is 1.34% and the corresponding SO 2
Read MoreBoiler Wet scrubber is a form of pollution control technology.. It includes removal from the suction of air stream which includes the harmful gases and dust particles by blower, the gaseous particles are removed by either chemical reaction or absorption of water. Our wet scrubber literally washes dust and smoke particles out of air.
Read MorePower plant boiler houses designed to burn coal or high sulfur oil are required by Federal and State pollution regulations to "scrub" (remove) sulfur dioxide from flue gasses to meet emission limits. SO2 in flue gasses is known to be harmful to the environment, as it is one contributor to the formation of acid rain. pH control is critical for the proper functioning of the scrubber system. | Yokogawa America
