INSTALLATION OF PREPARATION OF A FUEL FOR A BOILER ROOM Russian patent published in 2005 - IPC

FIELD: heat supply.

SUBSTANCE: the invention is pertaining to the field of the heat supply industry and is intended for preparation of fuel, in particular, petroleum for use in the boiler rooms being a source of a heat supply of remote settlements. The installation contains: a heater-evaporator, a heat exchanger for heating up a feed stock, the fuel feed stock pump and containers of the feed stock and collection of the light fractions. At that the installation is supplied with the second feed stock pump and three in series connected to each other heat exchangers of the light fractions condensation, the first and second feed stock pumps are connected by their inlets to a feed stock container. The outlet of the first feed stock pump is connected through the feed stock heating up heat exchanger to the heater-evaporator, which by its vapors outlet is connected to the first out of three in series connected to each other heat exchangers, the last of which is connected to its container of the light fractions condensate collection. The outlet of the second feed stock pump is connected in parallel to the heat exchangers of condensation of the light fractions and through them to the heater-evaporator. Each of heat exchangers in parallel connected to each other is supplied with a thermoregulator to keep in it a constant temperature of condensation of the light fractions vapors. The first and second of in series connected heat exchangers are connected through the placed in the feed stock container coiled pipes each to its container of the light fractions collection. The heater- evaporator through the feed stock heating up heat exchanger is connected to the container for fuel collection. In the result the invention allows to upgrade quality of the fuel preparation for the boiler plants at simultaneous production of several light fractions of the feed stock, mainly petroleum. The invention ensures improvement of the quality of the fuel preparation for the boiler plants at simultaneous separate production of several light fractions of a feed stock, mainly petroleum.

EFFECT: the invention ensures improvement of the quality of the fuel preparation for the boiler plants at simultaneous separate production of several light fractions of the feed stock, mainly petroleum.
