The following measures should be taken to reduce the heat loss of gas-fired boiler

（1)降低排煙熱損失：應控製合理的過量空氣係數；減少爐膛和煙道各處漏風；製粉係統運行中盡量少用冷風和消 除漏風；應及時吹灰、除焦，保持各受熱麵，尤其是空氣預熱器受熱麵清潔，以降低排

(1) To reduce the heat loss of exhaust gas, reasonable excess air coefficient should be controlled; Reduce air leakage in furnace and flue; During the operation of pulverizing system, cold air should be used less and air leakage should be eliminated; Soot blowing and coke removal should be carried out in time to keep all heating surfaces, especially the heating surface of air preheater, clean, so as to reduce the emission

煙溫度；送風進風應盡可能采用爐頂處熱風或尾部受熱麵夾皮牆內的熱風。

Smoke temperature; The hot air at the top of the furnace or in the skin wall of the heating surface at the tail should be used as far as possible.

(2)降低化學不完全燃燒熱損失：主要保持適當的過量空氣係數，保持各燃燒器不缺氧燃燒，保持較高的爐溫並使燃料與空氣充分混合。

(2) To reduce the heat loss of chemical incomplete combustion, it is mainly to keep the appropriate excess air coefficient, keep the burners burning without oxygen loss, keep the furnace temperature high and make the fuel and air fully mixed.

(3)降低機械不完全燃燒熱損失：應控製合理的過量空氣係數；保持合格的煤粉細度；爐膛容積和高度合理，燃燒器結構性能良好，並布置適當；一、二次風速調整合理，適當提高二次風速，以強化燃燒；爐內空氣動力場工況良好，火焰能充滿爐膛。

(3) To reduce the heat loss of mechanical incomplete combustion, the reasonable excess air coefficient should be controlled; Keep the qualified fineness of pulverized coal; The volume and height of the furnace are reasonable, the structure and performance of the burner are good, and the layout is appropriate; 1、 The secondary air speed should be adjusted reasonably, and the secondary air speed should be increased appropriately to strengthen the combustion; The working condition of the aerodynamic field in the furnace is good, and the flame can fill the furnace.

(4)降低散熱損失：要維護好鍋爐爐牆金屬結構及鍋爐範圍內的煙、風管道，汽水管道，聯箱等部位保溫。降低排汙熱損失：保證給水品質，降低排汙率。

(4) Reduce heat loss: maintain the metal structure of boiler wall and the thermal insulation of flue gas, air pipe, steam water pipe, header and other parts within the scope of boiler. Reduce the heat loss of sewage: ensure the quality of water supply, reduce the sewage rate.
