摘要： A compact fire tube boiler (200) comprises: a first heat transfer zone (202) having a furnace (212) which receives flue gases having a pressure between 500-2000 mmWC and combusts a fuel therein, to generate flue gas at a temperature between 1300-1400 °C, wherein, in the first heat transfer zone (202), 30-35% of heat is extracted; a second heat transfer zone (206) having convective tubes (222) principally adapted to transfer the hot flue gases from the first heat transfer zone (202) to a third heat transfer zone (204) while extracting only 10-15% of heat therefrom; and the third heat transfer zone (204) which is the main convective pass having convective tubes (224), extracts 55-60% of heat therein. The compact fire boiler (200) reduces power consumption by 60-80% and footprint by 30%.

摘要： Method for the recovery of heat from products of combustion comprising the following steps: (i) increasing the velocity of the hot flue gases by feeding compressed air powered by a turbo charger/turbo compressor (6) to the fuel, in the burning stage; (ii) subject the fuel cum high pressure air to a step of burning (14) in an enclosure (8); (iii) adjusting the fuel burning rate vis-à-vis the quantity/pressure of air; (iv) producing and maintaining a small steady flame; (v) indirectly transferring a small part of the heat of combustion to a relatively colder external fluid (15) surrounding said burning enclosure; (vi) passing the products of combustion through a first heat exchanger (11); (vii) indirectly transferring heat by convection in said first heat exchanger (11) to the external fluid (15); (viii) passing the partly heat depleted flue gases coming out of said first heat exchanger (11) through a turbine (6b) said turbo charger/turbo compressor (6); (ix) indirectly-transferring further heat from said partly heat depleted flue gases in a second heat exchanger (12) to the external fluid (15).
