Product Description
Structure characteristic

The boiler is small and compact. Thread smoke tubes replaces smooth tubes, then the tubes heat transfer efficiency is 1.7-1.8 higher than previous, which decreases boiler required heating surface and boiler volume. This makes the boiler easier to transport, layout, install and reduces engineering cost.
The boiler mainly adopts thread smoke tubes as convection heating surface. The tubes is laid inside the boiler drum. Then the boiler has a compact structure and prevents cool air permeating into smoke side. Less air leakage lows exhaust smoke loss and improve boiler efficiency.
Arch tube plate and one-pass thread smoke tube inside the drum effectively avoids tube sheet crack during operation.
Wing flue covers drum bottom effectively avoids drum bottom deformation during operation.

Design characteristics
Soot inertial separation device is set inside boiler and Big volume natural sedimentation chamber is set on the rear arch top. Smoke flow speeds is slow here, some particles in the smoke can be separated out because of gravity. The smoke turns fast at the head of wing flue, and many particles are separated out because of inertia. It lows original emission concentration. The ash in the rear arch can fall on the grate by ash falling hole, then be removed, which decreases secondary pollution. The boiler operates well and turns out that the original emission concentration is less than 2000mg/Nm³. Besides, with the equipped high efficiency dust collector, the boiler emission concentration satisfies national 1-class standard.

The intense radiation furnace arch can form reasonable 'A' style fire to prompt the combustion. Water cooling wall forms furnace upon the grate. It is big enough to burn the coal completely. The reasonable arch arrangement ensures flow speed. Meanwhile, the inside thread smoke tube, high efficient burning device, well-designed arches and high quality insulation materials and other characteristics ensure the boiler thermal efficiency is higher than national standard.

All the circulation are independent and simple, which greatly avoid water cooling wall crack.

Performance characteristics


In design perspective, we design bigger contribution allowance. Our verifying calculation turns out that the contribution allowance is more than 10%. The boiler operation practice indicates that the use of high efficient heat transfer component----thread smoke tube with enough screw thread makes the boiler output 10% high than nameplate rated capacity.
The equipment operates stably. The reasonable smoke speed enable no ash deposition on the thread smoke tube in the operation. So the boiler output and thermal efficiency won't decrease along with the long operation time. As a result, the boiler can keep ideal sustainable output and efficient.

Heat efficient
The sufficient heating surface enables the fuel heat be absorbed amply. Calculation shows that smoke exhaust temperature is at 160ºC. On the other hand, we arrange furnace arch and furnace wall reasonably. The furnace wall is tight while the expansion seam is rational, which decrease cool air leak into boiler. The boiler thermal efficiency is up to 80%.
Flexible load regulation
Big water volume, high heat storage capacity, nearly 1/3 drum heating surface with many high efficiency thread smoke tube inside the boiler drum apparently reduce boiler heating time.
