D88尊龙一,要先選好廠家。目前,市面上沼氣發電機組種類繁多,大致說,有專業依照燃氣特性設計制造和柴油發起機簡單改造兩種。燃氣發起機運用的燃氣,特別是沼氣由于燃氣壓力和濃度是時辰變化的,并且燃氣在氣缸做功時熄滅工況也比燃油惡劣得多,這就請求發起機必需順應燃氣熄滅工況,并且對燃氣和空氣比例、壓力適時調理,有圓滿的熄滅控制技術,以及常年研發積聚的經歷和數據。

D88尊龙Firstly, we should select the manufacturer first. At present, there are many kinds of biogas generating units on the market. Generally speaking, there are two kinds of specialized design and manufacture according to gas characteristics and simple modification of diesel engine. Gas, especially biogas, is used by Gas Starters because of the time-varying pressure and concentration of gas and the worse extinguishing condition of gas when the cylinder is working, which requires that the starter must comply with the extinguishing condition of gas, adjust the gas-air ratio and pressure timely, have a satisfactory extinguishing control technology, as well as the experience and data accumulated through years of research and development. 。

二,選擇合理、經濟的控制程度。普通來說,專業廠家都會有不同配置的設備可供選擇,如普通根本型、全自動管理型和全自動操作型三種控制系統。普通根本型機組能夠做到機組正常運轉;全自動管理型裝備電腦管理控制系統,能夠全方位直觀顯現運轉工況,自動保管運轉數據,并且能夠在電腦上下達指令操控機組;全自動控制系統是國際一流品牌相當水準的控制系統,除具有全自動管理功用外,機組自動運轉,自動調整各項運轉參數,關鍵部件全部采用高端進口產品,牢靠性高。

D88尊龙Second, choose reasonable and economic control degree. Generally speaking, professional manufacturers will have different configurations of equipment to choose from, such as ordinary basic type, fully automatic management type and fully automatic operation type of three control systems. Ordinary basic units can achieve normal operation of the unit; fully automatic management equipment computer management control system, can fully visualize the operation conditions, automatically store operation data, and can command and control the unit on the computer; fully automatic control system is an international first-class brand equivalent level of control system, in addition to full automatic management function, automatic operation of the unit Turn, automatically adjust the operation parameters, all the key components are high-end imported products, high reliability.

D88尊龙三,依據氣量選好機型。普通來說,國產燃氣內燃發電機組發電熱效率在25%~39%,專業性、機型不同,發電效率不同。首先要肯定沼氣熱能幾,它與沼氣總量,單位沼氣熱量有關。由于沼氣成分主要以甲烷、二氧化碳為主,因而,單位沼氣熱量僅思索甲烷熱量。

D88尊龙Thirdly, choose the model according to the gas volume. Generally speaking, the thermal efficiency of domestic gas-fired internal combustion generating units ranges from 25% to 39%. The power generation efficiency varies with the specialty and type of engine. Firstly, we should affirm the heat energy of biogas, which is related to the total amount of biogas and the heat per unit of biogas. Because methane and carbon dioxide are the main components of biogas, the unit heat of biogas only considers the heat of methane.

D88尊龙四,搞好電站規劃、設計和建立。首先應該契合國度電力建立平安請求,最好能請具備專業學問、有經歷的設計單位提供設計,設計過程要充沛分離現場條件,以盡可能的儉省投資,充沛發揮發電機組的效能。

Fourth, do a good job in the planning, design and establishment of power plants. Firstly, it should be in line with the request of national electric power to establish safety. It is better to invite design units with professional knowledge and experience to provide design. The design process should be fully separated from the site conditions so as to save investment as much as possible and give full play to the efficiency of generating units.
