影響1噸燃氣鍋爐燃燒狀態因素有哪些？
What are the factors affecting the combustion of a ton of gas boilers?
一是1噸燃氣鍋爐爐排面積小。該爐排寬度不能使單位時間內進入爐排的燃料達到該設計參數下所需的耗煤量，即鍋爐產生熱量和高溫煙氣量與設計出力要求的遠遠不足，其結果必然是壓力、蒸發量偏離設計值。
One is the floor area is small. The width of the grate cannot make fuel per unit time into the grate, under the design parameters required in coal consumption, namely the boiler heat and high temperature smoke gas output requirements and design the enough, the result must be pressure, evaporation deviates from the value of the design.
二是往復平推爐排煤層厚度受限制。由于爐排較窄，相應減小了煤耗，為了增加燃煤量，只有增加爐排上煤層厚度。由于是往復平推爐排，煤在爐排上無自然下落趨勢，只靠爐排片翹起向后推動使煤在爐排上燃燒，然而煤層過厚，爐排片對煤，特別是超過規定厚度煤層推動作用減弱，當活動爐排抽回時，又將剛向后推動的煤帶回，使煤層向后運動產生停滯，以至煤及渣混合起鼓，不能及時將煤渣推入渣坑，嚴重時，可使燃煤及渣頂著后拱，破壞了層燃狀態，影響正常運行。
The second is the thickness of the coal seam in the back and forth. Because the grate is relatively narrow, the coal consumption is reduced accordingly, to increase the amount of coal burning, only the coal seam thickness is added to the furnace. As reciprocating horizontal pushing grate, no natural falling trend of coal on the fire grate, powered by backward link cock only make coal burning in the grate, too thick coal seam, however, grate piece of coal, especially in excess of the prescribed role in promoting the thickness of coal seam is abate, when activities grate withdraw, just pushing coal back to back, it will make the coal seam backward movement stagnation, and slag and coal mixing drum, can't timely pushing coal slag into the pit, serious when, can make the coal and slag with arch, destroyed the layer combustion state, affect the normal operation.
三是爐排長度不夠，縮短了燃煤在爐排上停留時間，特別是在增加煤層厚度時，爐排行程、爐排推動頻率不變，致使煤不能充分燃燒，爐渣中含有大量可燃質，增加了機械不完全燃燒熱損失。
Is a grate length is insufficient, shorten the retention time on coal burning in the grate, especially in the increase of coal seam thickness, grate stroke, grate drive frequency constant, which is not fully burning coal, slag containing large amounts of combustible qualitative, increased the mechanical incomplete combustion heat loss.
四是前后拱結構不合理，燃燒達不到最佳狀態。前后拱配合不當，燃盡區的高溫煙氣，被引導作用不明顯，拱不能保證爐膛有較高溫度，主燃區得不到應有的熱量，煤燃不透;同時后拱覆蓋爐排面積較大，拱型結構使高溫煙氣流動受阻，削弱了擾動，縮短煙氣流程，同時造成喉部高溫煙氣中未燃物與空氣混合不良，增加了化學燃燒損失。
Fourth, the arch structure is irrational and the combustion is not the best. Arch mismatch, before and after the high temperature flue gas of burning area, be directed effect is not obvious, arch cannot ensure furnace with high temperature, primary zone without proper heat, coal combustion opaque; At the same time after the arch cover fire grate area is larger, the arch structure makes high temperature flue gas flow is blocked, weaken the disturbance, shorten the flue gas flow, at the same time cause the throat not combustion in high temperature flue gas and air mixture, increased chemical combustion loss.
