选择沼气内燃发电机组选择参考的条件有哪些?

一,要先选好厂家。目前,市面上沼气发电机组种类繁多,大致说,有专业依照燃气特性设计制造和柴油发起机简单改造两种。燃气发起机运用的燃气,特别是沼气由于燃气压力和浓度是时辰变化的,并且燃气在气缸做功时熄灭工况也比燃油恶劣得多,这就请求发起机必需顺应燃气熄灭工况,并且对燃气和空气比例、压力适时调理,有圆满的熄灭控制技术,以及常年研发积聚的经历和数据。

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,选择合理、经济的控制程度。普通来说,专业厂家都会有不同配置的设备可供选择,如普通根本型、全自动管理型和全自动操作型三种控制系统。普通根本型机组能够做到机组正常运转;全自动管理型装备电脑管理控制系统,能够全方位直观显现运转工况,自动保管运转数据,并且能够在电脑上下达指令操控机组;全自动控制系统是国际一流品牌相当水准的控制系统,除具有全自动管理功用外,机组自动运转,自动调整各项运转参数,关键部件全部采用高端进口产品,牢靠性高。

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.

三,依据气量选好机型。普通来说,国产燃气内燃发电机组发电热效率在25%~39%,专业性、机型不同,发电效率不同。首先要肯定沼气热能几,它与沼气总量,单位沼气热量有关。由于沼气成分主要以甲烷、二氧化碳为主,因而,单位沼气热量仅思索甲烷热量。

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.

四,搞好电站规划、设计和建立。首先应该契合国度电力建立平安请求,最好能请具备专业学问、有经历的设计单位提供设计,设计过程要充沛分离现场条件,以尽可能的俭省投资,充沛发挥发电机组的效能。

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.
