一、定義：
全自動生物質熱水鍋爐生物的一個種類，就是以生物質能源做為燃料的鍋爐叫生物質鍋爐，分為生物質蒸汽鍋爐、生物質熱水鍋爐、生物質熱風爐、生物質導熱油爐、立式生物質鍋爐、臥式生物質鍋爐等。
二、分類：
生物質鍋爐分為臥式生物質鍋爐，立式生物質鍋爐。生物質燃氣導熱油爐，生物質蒸汽鍋爐，生物質熱水鍋爐，生物質導熱油爐。
三、定壓方式：
全自動生物質熱水鍋爐供熱系統中的定壓方式：在高溫熱水供給系統中，由于水溫高于常壓下水的飽和溫度，因而，系統中壓力應當堅持高于相應供水溫度的飽和壓力，這樣才能夠避免熱水汽化和發作水沖擊。水是不可緊縮的流體，一旦走漏就會降壓;相反，水加熱又 會體積收縮，假如不能穩定壓力，也會毀壞供熱系統中的設備。由此，為了避免降壓汽化和收縮升壓，高溫熱水系統必需穩定系統內的壓力，這就是定壓。熱水供熱系統的定壓方式有以下幾種：
1），采用高架水箱定壓方式
這種方式的定壓點設在熱水循環泵入口或回水主干線上，安裝僅僅為一只高架水箱，其構造簡單，工作穩定牢靠，能穩定系統壓力，并能滿足系統網絡的溢水和補水請求。在這種系統中，水箱裝置高度必需滿足使系統中最高點不汽化的請求。因而，裝置位置較高。這種定壓方式適用與供熱范圍不大的低溫水供熱系統中。
2），采用補給水泵定壓方式
