Steam Boilers
From Boilers
Waste Heat Recovery Systems are designed for pressure drop on exhaust gas side as per maximum permissible back pressure of source equipment.
Adequate margin for rise in
pressure drop in Waste Heat Recovery System due to soot accumulation is provided to prolong the time between two successive cleaning operations.
It is well known that Waste Heat Recovery System has large potential savings in fuel cost for the fired equipment. Payback period is very attractive.
Optimized thermal design (with economizer for Boilers) ensures maximum heat recovery from exhaust gases.
The heating surface of the system is provided with adequate margin for fouling on exhaust gas side. This ensures that heat recovery is not affected by soot accumulation on tubes within reasonable limits.
Design
Boilers designs for individual client’s requirements, heat recovery boilers can be horizontal or vertical, fire tube or water tube and single or two pass.
Boilers are designed for easy maintenance and repair as per ASME codes.
Refractory lined where required and 80 to 160 Kg Rock wool jacketed with M.S. Color Sheet or S.S. sheet where required.
