DHL系列角管式水管鍋爐是我國通過聯合國GEF項目、從丹麥沃倫公司引進的一種新穎結構的鍋爐，是在四角上布置有不受熱的下降管且有自支撐作用、鍋筒一般布置成爐前橫置式或單鍋筒型的一種水管鍋爐的商業名稱。
我公司通過與西安交通大學聯合設計及獨立開發，已掌握該爐型的基本原理，產品性能和制造工藝，結合我國燃煤特性，不斷消化吸收、改進研究和開發，已經形成了具有我公司特色的角管式蒸汽鍋爐系列產品和角管式熱水鍋爐系列產品，目前，江蘇四方鍋爐有限公司制造的該型鍋爐已遍布全國各地。
角管鍋爐采用模式壁結構，既可減少漏風，又能采用輕型敷管爐墻，不用笨重的耐火和保溫磚墻，蓄熱量小，時間短。
角管鍋爐采用獨特的水循環結構，an全可靠。角管鍋爐為自支撐結構，無鋼架，抗震性能好。角管鍋爐采用正轉橫梁式鏈條爐排結構，等壓統倉送風，適用寬煤種設計。
角管鍋爐熱效率高，負荷調節范圍廣，運行成本低，且故障率低，能長期無故障運行。
角管鍋爐安裝工作 量少，安裝周期短，且占地面積小，工建成本低。
角管式鍋爐作為我國燃煤鏈條鍋爐的更新換代產品，以其優異的先進節能特性，已成為我公司參與市場競爭的拳頭產品。
DHL series of corner pipe water boiler is our country through the United Nations GEF project, introduced from Warren, Denmark, a novel structure of the boiler, is arranged in the four corners of the pipe is not heated down and self-supporting function, the drum is generally arranged A commercial name for a water tube boiler with a horizontal or single drum type.
Through joint design and independent development with Xi'an Jiaotong University, our company has fully mastered the basic principle, product performance and manufacturing process of the furnace, combined with the characteristics of coal burning in our country, constantly digest and absorb, improve research and development, has formed a company with my company Characteristics of the angle tube steam boiler products and the angle of the tube hot water boiler products, at present, Jiangsu Sifang Boiler Co., Ltd. to create the boiler has been throughout the country.
Corner tube boiler wall mode, can reduce air leakage, but also the use of lightweight pipe wall furnace, without bulky fire and insulation brick wall, heat storage is small, time is short.
Corner tube boiler uses a unique water cycle structure, safe and reliable. Corner tube boiler self-supporting structure, no steel frame, good seismic performance. The angle tube boiler adopts the structure of the forward crossbeam chain grate, and the isobaric pressure blows air for wide coal type design.
Corner tube boiler has high thermal efficiency, wide range of load regulation, low operation cost and extremely low failure rate, which can run long-term trouble-free.
Corner tube boiler installation work less, the installation cycle is short, and covers an area of small, low cost of construction.
As the replacement of coal-fired chain boiler in our country, the corner-tube boiler has become the fist product of our company participating in the market competition with its excellent advanced energy-saving features.
