烟尘分离

炉膛惯性分离烟尘，原始排放浓度低于国家标准。降低烟尘排放浓度。

Smoke-dust separation

The furnace separates the smoke and dust inertially. The original emission concentration is lower than the national standard, which decreases the smoke dust emission concentration.

螺纹烟管

强化传热，缩小锅壳尺寸、提高柔性，从而减小管端焊缝热应力，不积灰，防止管板开裂。

Threaded fire tube

The threaded fire tube enhances heat transfer, narrows the shell size and increases the flexibility, which reduces the thermal stress of the welding seam of the tube tip and prevents the crack of the tube plate.

拱形管板

提高管板柔性，从而减小管端焊缝热应力，取消拉撑件，防止管板开裂。

The arched tube plate

The arched tube plate can increase the flexibility of the tube plate, which reduces the thermal stress of the welding seam of the tube tip. The tension brace parts are removed to prevent the crack of the tube plate.

八字烟道

降低高温管板烟温，从而防止过冷沸腾，减少锅炉底部热负荷，防止管板开裂，防止鼓包。

Wing shaped flue

It can reduce the smoke temperature of the high -temperature tube plate to avoid the boiling for over cold boiling. It can also decrease the heat load at the bottom of the boiler to avoid the crack of the tube plate and the bumps.

承载风箱不漏煤炉排

可使锅炉房更简洁美观；不漏煤炉排强化锅炉燃烧，提高燃烧效率，提高经济性。

No- coal -leakage grate with bellows

It can make the boiler room look simple, tidy and nice. The non -leakage grate can strengthen the boiler combustion, improve combustion efficiency and be more economical.

回水引向高温管板

提高高温管板水流冲刷速度，降低水温，从而防止过冷沸腾，防止管板开裂。

Return water flowing to the high temp. tube plate

This can increase the scouring velocity of the current of water and decrease the water temp. to prevent the over cold boiling and the crack of the tube plate.

引射管

提高水冷壁水流速度，从而防止过冷沸腾，防止爆管。水循环更加可靠。

Induction tunnel

Increase the current of water velocity to prevent the over cold boiling and the tube explosion. The water circulation becomes more reliable.
