Steam Coal Gasifier Plant

Owing to our vast experience, we have been successful in catering to the requirements of our clients by offering Steam Coal Gasifier Plant. These plants are used to collect the gas extracted from coal. The producer gas is very combustible and environment-friendly, therefore, widely used for direct combustion as well as for operating machines in various industries. We manufacture these plants from best-in-class components and stainless steel that are brought from the trustworthy vendors of the market. The Steam Coal Gasifier Plant is available in different specifications as required by our customers.Other details:The combustible gases from the gasifier can be usedFordirect and Indirect heat applications.However in order for the gas to be used for any of the above applications it should be cleanedof tar and dust and be cooled. As previously mentioned cooling and cleaning of the gas isone of the most important processes in the whole gasification system. The failure or thesuccess of producer gas units depends completely on their ability to provide a clean and cool gas to the engines or for burners. Thus the importance of cleaning and cooling systems cannot be overemphasized.The temperature of gas coming out is normally between 300-500.This gashas to be cooled in order to raise its energy density. Various types of cooling equipment havebeen used to achieve this end.Most coolers are gas to air heat exchangers where the coolingis done by free convection of air on the outside surface of heat exchanger. Since the gas alsocontains moisture and tar, some heat exchangers provide partial scrubbing of gas.Thus,ideally the gas going to an internal combustion engine should be cooled to nearly ambient temperature. Cleaning of the gas is trickier and is very critical. Normally three types of filters are used in this process. They are classified as dry, moist and wet.In the dry category are cyclone filters. They are designed according to the rate of gasproduction and its dust content.The cyclone filters are useful for particle size of 5m andgreater.Since 60-65% of the producer gas contains particles above 60m in size thecyclone filter is an excellent cleaning device.After passing through cyclone filter the gas still contains fine dust particles and tar. It isfurther cleaned by passing through either a wet scrubber or dry cloth filter. In the wetscrubber the gas is washed by water in counter current mode. The scrubber also acts like acooler, from where the gas goes to cloth filter for final cleaning.Since cloth filter is a fine filter, any condensation of water on it stops the gas flow because ofincrease in pressure drop across it. Thus in quite a number of gasification systems the hotgases are passed through the cloth filter and then only do they go to the coolerSince thegases are still above dew point, no condensation takes place in filter.
