Abstract

Instalacja energoefektywnego obniżenia emisji metanu w powietrzu wentylacyjnym, zwłaszcza z kopalni węgla kamiennego, ma otwór szybu wentylacyjnego (16) i przerywacz ciągu (16-1) objęty jest okapem (16-2) wyposażonym w wentylator odciągowy (14-1), a okap (16-2) stanowi część wlotową systemu kanałów (17) powietrza spalania połączonych bezpośrednio lub pośrednio do komory spalania (3) kotła (1), a wentylator odciągowy (14-1) powietrza wentylacji ma nadrzędny układ regulacji ciśnienia w przestrzeni przerywacza ciągu powietrza przez zmianę prędkości obrotowej wentylatorów natomiast para dodatkowych wentylatorów (14-2), ma podrzędny układ regulacji stosunku strumieni powietrza przez zmianę ich prędkości obrotowej. W systemie kanałów powietrza wentylacyjnego (17) zabudowane są nagrzewnice powietrza spalania (12-1) ogrzewane parą wodną i (12-2) ogrzewane skroplinami, a powietrze wtórne dopływa przez zespół dysz (18) rozmieszczonych na obwodzie paleniska (3) kotła (1) w strefach o temperaturze spalin powyżej punktu zapłonu metanu. Kanał spalin za kotłem (1) jest wyposażony w układ mokrego oczyszczania oparty na bezprzeponowym wymienniku (19-2) odzysku ciepła spalin zakończony emitorem (20) — kominem.The installation of energy-efficient reduction of methane emissions in the ventilation air, especially from coal mines, has a ventilation shaft opening (16) and the draft interrupter (16-1) is covered by a hood (16-2) equipped with an exhaust fan (14-1), and the hood (16-2) is the inlet part of the combustion air duct system (17) connected directly or indirectly to the combustion chamber (3) of the boiler (1), and the ventilation air exhaust fan (14-1) has a superior pressure control system in the air draft interrupter space by changing the rotational speed of the fans, the pair of additional fans (14-2) has a subordinate system of air flow ratio control by changing their rotational speed. In the ventilation air duct system (17), combustion air heaters (12-1) heated with steam and (12-2) heated with condensate are installed, and secondary air flows through a set of nozzles (18) located around the perimeter of the furnace (3) of the boiler (1). ) in zones with exhaust gas temperatures above the methane flash point. The flue gas duct downstream of the boiler (1) is equipped with a wet cleaning system based on a diaphragmless exhaust heat recovery exchanger (19-2) ending with an emitter (20) - a chimney.
