It is an important strategic deployment put forward by the central government to promote clean heating in winter in northern China. Recently, a clean energy central heating project with a total investment of 20 million dollars has been built in Hebei province, China. The project rectifies the old equipment and plans to use 2 sets of gas-fired hot water boilers to provide central heating for local residents. The requirements of the boilers are as follows:
The distributed energy system project built by the customer company provided electric energy and heat energy for the surrounding enterprises through the cogeneration unit of gas-steam combined cycle.
The customer company is mainly engaged in the production and sales of auto tires. The customer company wishes to convert the coal-fired boiler to natural-gas-fired boiler through technical transformation, eliminate the demand of coal.
The customer company mainly engaged in knitwear processing printing, dyeing, and sales and so on. Textile industry used to be one of the pollution-intensive industries in China. Nowadays, people's environmental awareness is increasing, which affects the development of industries towards high efficiency, energy conservation and environmental protection. When purchasing equipment for factories, the company also emphasized the necessity of energy saving and environmental protection. In this regard, ZOZEN Boiler specially recommended YY(Q)L series vertical oil (gas) fired thermal oil heater.
