河南力威熱能設(shè)備制造有限公司15噸SZL生物質(zhì)鍋爐又名雙鍋筒縱置式鏈條爐排鍋爐，燃用生物質(zhì)或固體成型燃料。爐膛兩側(cè)墻水冷壁采用膜式水冷壁結(jié)構(gòu)；做工精良，用料扎實，注重細(xì)節(jié)，從精細(xì)化設(shè)計到材料生產(chǎn)，工藝嚴(yán)苛，精益求精。該15噸生物質(zhì)鍋爐爐膛兩側(cè)墻水冷壁采用膜式水冷壁結(jié)構(gòu)；爐膛前、后墻水冷管向下延伸到爐排上部，形成前后拱。增加鍋爐的密封性，同時增加了爐膛容積和受熱面積，加固了后拱的強(qiáng)度。

SZL型組裝水管鍋爐，采用雙鍋筒縱置式布置，燃燒方式為鏈條爐排。額定蒸發(fā)量4～25t/h不等，上圖鍋爐蒸發(fā)量為15t/h。鍋爐燃用生物質(zhì)成型固體燃料。爐膛兩側(cè)墻水冷壁采用膜式水冷壁結(jié)構(gòu)；爐膛前、后墻水冷壁管向下延伸到爐排上部形成前后拱，這樣既增加鍋爐的密封性能，又增加了爐膛容積及受熱面，同時加固了后拱的強(qiáng)度。爐膛后為燃燼室、對流管束，尾部有省煤器。煙氣經(jīng)爐膛、燃燼室、對流管束、省煤器進(jìn)入尾部煙道，通過除塵器、引風(fēng)機(jī)、煙囪排入大氣。前墻布置有二次風(fēng)，由閥門控制，在燃用生物質(zhì)燃料時投入使用，強(qiáng)化燃燒，使燃料充分燃盡，提高燃燒效率。采用較高的進(jìn)料口，以滿足生物質(zhì)燃料的需要。

本鍋爐分上下兩大件出廠，上部大件包括鍋爐本體、上部鋼架及上部爐墻，下部大件包括煤斗、鏈條爐排、下部爐墻及內(nèi)部通風(fēng)道，除前后拱管及其連接管現(xiàn)場裝配，部分磚墻及前后爐拱在現(xiàn)場砌筑外，其余部件均組裝出廠，尾部省煤器及煙風(fēng)道隨鍋爐配套出廠。尾部除塵器及其接管按照合同發(fā)貨。

燃燒系統(tǒng)部分：燃燒系統(tǒng)包括煤斗、鏈條爐排、爐排傳動裝置。

本鍋爐鏈條爐排為大塊爐排片。爐排下面劃分為數(shù)個獨立的風(fēng)室，根據(jù)燃燒情況配風(fēng)，進(jìn)風(fēng)方式為雙側(cè)進(jìn)風(fēng)，進(jìn)風(fēng)均勻。前墻布置有二次風(fēng)，由閥門控制，在燃用生物質(zhì)燃料時投入使用。 爐膛前部設(shè)有料斗、閘門，用以調(diào)節(jié)進(jìn)入爐排的料層厚度。爐排速度由減速箱控制調(diào)節(jié)。燃燒后的爐渣排入渣斗。

SZL系列水冷拱、膜式水冷壁組裝鍋爐是一種新型水管組裝鍋爐，它將大型鏈條爐排鍋爐燃燒系統(tǒng)水冷拱技術(shù)及膜式水冷壁技術(shù)巧妙應(yīng)用到組裝鍋爐上，技術(shù)指標(biāo)處于國際水平。

SZL series shop-assemble water tubes boiler, which is a vertical type with double drums, uses chain grate as its combustion mode with rated evaporative capacity: 4-20t/h. this boiler uses shaped and solid biomass fuel, the two sides of whose furnace adopt membrane water-cooled wall structure. The tubes of water-cooled wall go down to the up side of the furnace which forms the front and rear arches so that the seal structure and intensity of back arch are enhanced and the cubic of the furnace and heating surface are enlarged. There are end combustion chamber and convection tube tank in the back of the furnace with fixing an economizer in the rear. After through the furnace, end combustion chamber, convection tube tank and economizer, the flue gas came into the flue duct in the rear, and then went by dust precipitator, induced draft fan &chimney, and was discharged into the air in the end. There is secondary air laying out in the front wall, which is controlled by valves and could be put into service to enhance the combustion and increase the combustion efficiency when using biomass fuel as boiler fuel. The height of feeding inlet is higher than usual to satisfy the need for biomass fuel.

This boiler is divided into two parts  the upper part and the lower part before leaving the factory. The upper part involves boiler proper, steelwork and upper boiler setting, while the lower part involves coal hopper, chain grate, lower boiler setting and internal ventilating duct. Except site-assembled tubes of front & rear arches including its connection tubes and site-built part of the boiler setting with front & rear arches, the rests are packaged for duty with its economizer in the tail part and flue duct before leaving the factory, while the dust precipitator in the tail part and its connection tubes would be delivered according to the contract.

Combustion system:Combustion system involves coal hopper, chain grater and transmission device.

This boiler adopts mass fire grate flakes. And the wind is fed from both sides of the boiler by several independent air chambers below the grate to make flow uniform overall, which could be adjusted in accordance with the burning condition. There is secondary air laying out in the front wall, which is controlled by valves and could be put into service when using biomass fuel as boiler fuel. The feeder hopper and valves are installed in the front part of the furnace to regulate the thickness of the materials on the grate, whose speed is controlled by reduction box. Finally, after combustion, the slag will be discharged into the slag hopper.

SZL series water-cooled arch and membrane water wall assembly boiler is a new type of water pipe assembly boiler. It applies the water-cooled arch technology and membrane water wall technology of large chain grate boiler combustion system to the assembled boiler. The technical indicators are at the domestic leading level.
