鍋爐（lú）可是相當實用的設備！

　　鍋爐是一種能量轉換設（shè）備，向鍋爐輸入的能量有燃料中的化學能、電能（néng）、高（gāo）溫煙氣的熱能等形式，而經過鍋爐轉換，向外輸出具有一定熱能的蒸汽、高溫水或有機熱載體。多用於（yú）火電站、船舶、機車和工礦企業。

　　鍋爐的主要工作原理是一種利用燃料燃燒後釋放（fàng）的熱能或工（gōng）業生產中的餘（yú）熱傳遞給容（róng）器內的水，使水（shuǐ）達到（dào）所（suǒ）需要的溫（wēn）度或一定壓力蒸汽的熱力設備。鍋爐（lú）在“鍋（guō）”與“爐”兩部（bù）分同時進行，水進入鍋爐以後，在汽水係統中鍋爐受熱（rè）麵將吸收的熱量傳遞（dì）給水，使水加熱成一定（dìng）溫度和壓力（lì）的熱水或（huò）生（shēng）成蒸汽，被引出應用。在燃燒設備部分（fèn），燃料燃燒不斷放出熱量，燃燒產生的高溫煙氣通過熱的（de）傳播，將熱（rè）量（liàng）傳遞給鍋爐受熱麵，而本身溫度逐漸（jiàn）降低，最後由煙囪排出。

　　Boiler is quite practical equipment!

　　The boiler is a kind of energy conversion equipment. The energy input into the boiler is in the form of chemical energy, electric energy and thermal energy of high-temperature flue gas. After the boiler is switched over, steam with certain heat energy, high temperature water or organic heat carrier . Used for thermal power plants, ships, locomotives and industrial and mining enterprises.

　　The main working principle of the boiler is a thermal device that uses the heat released after combustion of the fuel or the waste heat from the industrial process to the water in the container to bring it to the desired temperature or a certain pressure of steam. Boiler in the "pot" and "furnace" at the same time in two parts, water into the boiler after the steam system in the boiler heating surface will absorb the heat transferred to the water, the water heated to a certain temperature and pressure of hot water or steam generated, was drawn application. In the combustion equipment section, the combustion of fuel continuously emits heat. The high-temperature flue gas generated by the combustion propagates through the heat and transfers the heat to the heating surface of the boiler, while the temperature of the fuel gradually decreases and finally is discharged from the chimney.
