Walia engineering associates pvt ltd and clean combustion pvt ltd manufacture steam boiler with their robust, versatile and high performance, multi-fuel firing boilers. Their multi-pass designs ensure high thermal efficiencies and with their fully independent circuits are ensured by their multi-pass designs, there is better turndown ratio and operational efficiency. Low maintenance and better heat transfer is achieved by their wet back design. Walia engineering associates has packaged steam boilers. These steam boilers are factory assembled for immediate delivery and commissioning which are highly compact and space saving with low installation costs. Various salient features of these boilers are: large water holding capacity for high thermal inertia and constant pressure; large steam water separation height for good quality steam; and good accessibility for ease of maintenance. These multi-fuel boilers can be fired using any conventional and unconventional fuels or its combinations like lignite, coal, agrowastes, municipal wastes, bagasse, oil, gas or any other specified fuels.
