摘要:
A boiler according to the invention contains an additional air channel (9) with an inbuilt fan (10) with adjustable output. The first end (9') of the additional air channel (9) is connected with the under-stoker space (11) located outside of the wind boxes (5) of the under-stoker wind boxes system (4). The second end (9") of the additional air channel (9) is connected with the atmosphere. Modernization of the existing boilers consists in installation in the described above method of an additional air channel (9) with an inbuilt fan (10).

A boiler according to the invention contains an additional air channel (9) with an inbuilt fan (10) with adjustable output. The first end (91) of the additional air channel (9) is connected with the under-stoker space (11) located outside of the wind boxes (5) of the under-stoker wind boxes system (4). The other end (9') of the additional air channel (9) is connected with either the space of the channel (6) supplying outside air to the wind boxes (5) or with the atmosphere or with the secondary air channel of the combustion chamber (2). Modernization of the existing boilers consists in installation in the described above method of an additional air channel (9) with an inbuilt fan (10). The method of elimination of uncontrolled leakages in a stoker-fired boiler consist in leading out and air, getting through air gaps, from the under-stoker space of the boiler located outside of the wind boxes (5) to the described above additional air channel (6), wherein current output of the fan (10) built into this channel is proportional to the current difference between temperature of air supplied to the wind boxes (5) and temperature of air in the additional air channel (6).

Bei einem Förderband-Rost für einen Brenner, umfassend eine vorgebbare Mehrzahl an entlang einer Förderrichtung gelenkig miteinander verbundenen Gliedern (3,4), wobei in Betriebslage in einem Brennbereich eine Brennfläche durch die Glieder (3,4) gebildet wird, wird vorgeschlagen, dass zwei benachbarte Glieder (3,4) ein Gliederpaar (7) mit einem ersten Glied (3) und einem zweiten Glied (4) bilden, dass bei dem Gliederpaar (7) im Brennbereich wenigstens ein Durchstromkanal (8) von dem ersten Glied (3) und dem zweiten Glied (4) berandet ist.

摘要:
A boiler is provided with a travelling mechanical grate (4) located in its furnace zone, with blast zones (5) and with a main air duct (6), delivering an atmospheric air into these zones (5) with help of a blast fan (7). In the under-the-grate space located under end section of the grate (4), having the length equalling from 10 to 40% of the total active length of the grate (4), there is at least one suction zone (8) connected with the first end (9) of the first additional air duct (10) Second end (11) of the duct (10) is connected with a source for negative pressure (12), which generates in the suction zone (8) a pressure lower than the pressure existing above the grate (4) by a value of range form 5 to 100 Pa. A method of modernisation of a typical stoker-fired boiler consists in cutting off of the at least one last blast zone (8) from the main air duct (6) and connecting this zone (8) over an additional air duct (10) with an adjusted negative pressure source (12) generating in this zone (8) a pressure lower than the pressure existing above the grate (4) by a value of range form 5 to 100 Pa. The method for reducing the particle matter emission consists in that in the under-the-grate space located under the end section of the grate (4), having a length equalling from 10 to 40% of the entire active length of the grate (4), a pressure is lowered in relation to the pressure existing above the grate (4) and the pressure difference is maintained in the range from 5 to 100 Pa.
