Distributed Energy System Application Cases
Distributed Energy System Application
Natural gas is one of the most important energy sources nowadays, and fossil fuels are becoming increasingly precious due to the continuous growth of energy demand. It is not only an ecological and environmental challenge, but also an economic challenge. The continuous rise in natural gas price requires us to maximize energy efficiency in the production of electricity, heat, and refrigeration. Distributed Energy System (DES) is a comprehensive energy supply system that uses CCHP (Combined Cold, Heat and Power) technology in a limited space to distribute the power generation system in a small-scale, small capacity modular, and decentralized manner near users through pipeline networks and cables. It can independently output electricity, heat and cold energy. Liyu regards itself as a comprehensive partner of customers, rather than just providing high-efficient and costeffective systems and gas generator set. We also provide professional consulting services and customer service to develop comprehensive cogeneration solutions for customers. By utilizing distributed natural gas energy supply to expand the entire value chain, our expertise in natural gas provides customers with continuous benefits.
Advantages of Liyu Gas Generator Set in CCHP Application
According to the scope of supply, distributed energy systems can be divided into Domestic Combined Heat and Power (DCHP) and Building Combined Heat and Power (BCHP).
Mainly aimed at various industrial, commercial or technological parks and other large areas. Equipment generally adopts the gas generator sets with large capacity, and external network equipment for cold and heat power supply shall also be considered, often requiring to construct independent energy supply centers.
The cooling and heating power supply system is built for buildings with specific functions, such as office buildings, commercial buildings, hospitals, and certain comprehensive buildings. Generally, only the gas generator set with small capacity is required, and arranged inside the building without considering external energy network construction.

Coal Seam Gas Application
Coal Seam Gas Application Cases
Coal seam gas is a symbiotic or associated gas that occurs in coal seams, mainly composed of methane, whose calorific value is equivalent to natural gas, belonging to unconventional natural gas. Burning coal seam gas for power generation through the gas generator set produces almost no exhaust gas, making it a clean and efficient energy source. Coal seam gas mainly includes three categories, namely Coal-bed methane (CBM), coal-mine methane (CMM) and abandoned mine methane (AMM). The composition of CBM and AMM allows these two types of coal seam gas to be directly burned in gas generator set without any technical issues. Due to the sudden changes of the composition of CMM produced during mining, higher requirements are taken on the design of gas generator set. However, Liyu has developed corresponding improved gas generator set for this kind of gas.
Coal Seam Gas Power Generation Solution
Due to the sudden changes of the composition of CMM produced during mining, higher requirements are taken on the design of gas generator set. The developed special gas mixing and internal-combustion engine control system can effectively apply this kind of coal seam gas. The gas generator set manufactured by Liyu can operate with low-pressure gas, and the generated electricity can meet the electricity power demand of mining, and can also be output to the public power grid, while the generated heat can be used for site heating demand or output to the regional heating system.
Advantages of Liyu Gas Generator Set in Coal Seam Gas Power Generation Application
Transforming hazardous gases into energy and improving the gas accident prevention capacity for safety benefits. Avoiding the release of methane into the atmosphere directly and effectively reducing greenhouse gases, in order to create good environmental benefits. As an high-efficient and clean energy source, commercializating it can create huge economic benefits.
Industrial Gas Application Cases
Industrial Gas Application
Industrial gas is used as fuel for gas engine after dehydration, dust removal, cooling (boosting if necessary), gasometer stabilization and pre-treatment. The gas engine drives the generator to generate electricity, and the denitration treatment would be done for engine exhaust gas when necessary to meet nitrogen oxide emission standards.
Industrial Gas Power Generation Solution
The gas generator set and its auxiliary systems (including cooling, air intake and exhaust, lubrication, etc.) can be integrated into a containerized power generation unit (commonly known as skid mounted design). Each containerized power generation unit is a small energy station that can generate electricity by connecting into industrial gas. Several of this can be combined into larger gas power plant.
