Machine of low carbon combustion introduces _ to exceed opportunity of low nitrogen combustion

Monomer type is full automatic combustion machine seems a flamethrower, enter blaze in season the chamber of a stove or furnace, inside the chamber of a stove or furnace implementation burns completely and the combustion of home of machine of combustion of; of output quantity of heat to the product spends completely determining undertake inside specific standard firebox. Regard combustion machine and boiler as the condition of standard experiment commonly so choose a condition. Include: The dimensional size of the chamber of a stove or furnace of; of air current pressure inside power; the chamber of a stove or furnace and geometrical appearance (diameter and length) . Aeriform motivation character matchs, point to the degree that satisfies these 3 requirements namely.

　　

　　 Combustion machinepower is when pointing to sufficient combustion, its can burn hourly how many quality (kilogram) or bulk (M3/h, below standard reference conditions) fuel, corresponding heat energy also gives out to output in the meantime (Kw/h or Kcal/h) . And of boiler demarcate is vapour crop, at the same time also quantity of line out specific fuel consumption, when choosing both must match.

　　

Inside an oily boiler, steam flows to begin from combustion machine, collect through the chamber of a stove or furnace, heat exchanger, flue gas implement with smoke evacuation canister the platoon comes atmosphere, constitute process of heating power of a fluid. The steam of the generation after combustion flows, upriver pressure head flows in passageway of the chamber of a stove or furnace, like be just like the water in the river, fall, head swims downward flow. The flow of mouth of the furnace wall as a result of the chamber of a stove or furnace, passageway, bend, plate washer, gorge and chimney to gas is existing obstruction, can cause pressure loss. If pressure head is insuperable the pressure loss of edge Cheng, flow cannot come true. Constant flue gas pressure must be kept in the chamber of a stove or furnace so, to saying to be pressed instead combustion machine, to leaving the boiler of wind device, after pressure of the chamber of a stove or furnace is considering loss of edge Cheng pressure head must pressure of prep above air.

　　

Turn over what the bulk that control is affecting combustion engine directly to exert oneself, the accident that presses the size that follows the chamber of a stove or furnace, flue instead and geometrical appearance are concerned. The pressure of the opportunity of boiler requirement combustion with great flow resistance wants tall, specific toCombustion machine, its pressure head has one value, corresponding air door, air flow position. When changing into integrity air door, wind force and pressure also change accordingly, of combustion machine exert oneself to also follow change. Pressure head of wind force hour is small, the pressure head when wind force is large is tall. To a specific boiler Shanghai, when incoming wind force is large, flow resistance greatens accordingly, make of the chamber of a stove or furnace press instead rise, of the chamber of a stove or furnace press instead rise to check again burn a wind force of machine like that, so, the effect of the size of its power curve, the chamber of a stove or furnace and geometrical appearance must know when choosing combustion engine

　　

To boiler, the dimensional size of the chamber of a stove or furnace, choose in what the thermic load intensity at the chamber of a stove or furnace decides above all when the design, according to it the cubage of OK and preliminary affirmatory the chamber of a stove or furnace.

　　

After dimension of the chamber of a stove or furnace is certain, still should determine its appearance and size, designing a principle is to make full use of the cubage; of the chamber of a stove or furnace avoids blind angle as far as possible, want to have certain deepness, reasonable flow direction, assure to have enough reaction time, make fuel burns completely inside the chamber of a stove or furnace, in other words, the flame that makes combustion machine ejective has enough retention period inside the chamber of a stove or furnace, because although oily mist bead is very small (0.01mm) , had mixed gas ignition before ejective combustion machine and begin to burn, but not quite sufficient. If the chamber of a stove or furnace is too shallow, retention period can produce incomplete combustion not quite, light person exhaust CO exceeds bid, risk black smoke again, power short of asks. Accordingly, when deciding deepness of the chamber of a stove or furnace, answer to accord with the accident of flame as far as possible, answer those who light type to still should increase the diameter of exit to the center, make sure circumfluence lights the bulk that gas institute constitutes. The geometrical appearance of the chamber of a stove or furnace basically affects the flow resistance of air current and radiant uniformity. A boiler wants to debug ability and combustion machine to have through what relapse match goodly.
