Igr,s exclusive association with china leading techonology, research, design & manufacturing company Tangshan leadshore in coal gasification offers complete plant and machinery for producer gas from coal gasifiers. Combustion matter in coal is converted into gaseous fuel, which is for heating purpose in rolling mills. Hot gas enables use of sensible heat, and no condensation of tar in pipeline when located close to reheating furnace. Detarred % dusted gas wherever requird is provided after when ever user unit is located at for away distance within premises, which can also berun on engine genset for power generation.
Advantage : 40% ENERGY COST SAVING COMPARED TO FUEL OIL
: Higher cost saving compared to natural gas/lpg
Application : re-rolling mills furnace
: ceramics kiln
: Heat treatment
: forging
- Single stage gasifies for hot producer gas
Body Structure: Whole body water jacket is adopted and side- producer steam is used for gasification. Top cover is casted with two kinds of refractory and heat insulation material;
COAL LOADING : Auto loading equipment with hydraulic drive is adopted, involving up-baffle and down belt unit for air tightness.
ASH REMOVAL : Ratchet wheel and pallet with hydraulic control is used to remove ash from both sides of gasifier. Grate is made of heat- resistant cast steel. Homogenous flow is by design.
MAIL GASIFIER
Jacketted steel vessel having boiler quality steel plate inside. Steam gets produced in water jacket of gasifier, which along with air is blown into hot solid fuel through grate having proper outlets for uniform distribution. Air + Steam is the gasifier media to convert solid fuel into combustible gas by partial oxidation and reduction process.
Coal Feed System : Coal is lifted by a hoister into bin of stoker. Hydraulic pressure device is adopted with uproller, middle plug and double bell loading system thereby preventing gas leakage.
Ash Removal :Ash in wet condition is removed intermittently by hydraulic device from both sides into wheel borrows, for disposal.

ADVANTAGES : |
|
APPLICATION : |
Awareness of using clean combustible gas generated from Coal is increasing day by day due to sharp increase in liquid fuel oil/natural gas cost in industry. Above hot gas is to be used directly for all industrial heating purpose closeto where gas is generated. Flame temperature up to 1500°C is attainable using the produced gas,and still higher temperature can be reached by preheating combustion air for its burning.
