Summary <strong>of</strong> country study – Bangladesh 141<br />

The fertilizer factory has two boilers with capacities to produce 180 tons/hr <strong>and</strong> 171 ton/hr <strong>of</strong><br />

steam, respectively. The steam generated at 60 bar <strong>and</strong> 510°C is ma<strong>in</strong>ly used <strong>in</strong> two<br />

backpressure steam turb<strong>in</strong>es to generate up to 11 MW <strong>of</strong> electricity. After <strong>part</strong>ial expansion<br />

<strong>in</strong> the turb<strong>in</strong>e, steam at 10 bar is used for process<strong>in</strong>g. Self-power generation <strong>and</strong> thermal<br />

energy consumption data <strong>of</strong> the factory are given <strong>in</strong> Figures 3.6 <strong>and</strong> 3.7, respectively.<br />

3.2.3 Assessment <strong>of</strong> the technical potential on the basis <strong>of</strong> questionnaire<br />

A survey <strong>of</strong> the different manufactur<strong>in</strong>g <strong>and</strong> commercial facilities <strong>in</strong> the country us<strong>in</strong>g<br />

technical criteria as def<strong>in</strong>ed by ESCAP’s prelim<strong>in</strong>ary assessment questionnaire allowed to<br />

make a very rough estimation <strong>of</strong> the technical <strong>cogeneration</strong> potential <strong>in</strong> the different subsectors<br />

(see Table 3.3), which amounted to almost 1,000 MW. More precise determ<strong>in</strong>ation<br />

would require more time <strong>and</strong> resources, which was beyond the scope <strong>of</strong> this study.<br />
