Two ways to improve the thermal efficiency of condensing boilers

To put it bluntly, to improve the thermal efficiency of the condensing boiler is to save money for the enterprise. However, what can be done to improve the thermal efficiency of the condensing boiler. Based on years of experience in the boiler industry, FANGKUAI Boiler concluded that boiler efficiency and pipe network transmission efficiency are the key to implementing energy conservation, and that reasonable use of machinery and equipment in strict accordance with relevant points can achieve better heating effect and improve The efficiency of the equipment, and consumers want to more reliably improve the efficiency of the heating of the condensing boiler should also follow this principle.

1. Improve boiler efficiency.
Condensing boiler efficiency is not the rated efficiency of a single boiler, but the seasonal efficiency of the condensing boiler group (group). In order to improve the seasonal efficiency, it is necessary to minimize the number of starts, stops and standby time of each condensing boiler during the heating period. This is because each time the boiler is started and stopped, it is subjected to purging to consume heat. In the standby time, the condensing boiler is equivalent to a large radiator and also causes heat loss. In order to improve the seasonal efficiency of the boiler group (group), the design selection configuration is very important. When selecting the model, it is necessary to consider how the boiler combination has better variable load regulation capacity and promote the minimum output of the boiler to match the minimum load.

2. Improve the efficiency of pipe network transportation.
There are three factors affecting the efficiency of the condensing boiler pipe network, namely heat loss caused by heat preservation, leakage and hydraulic imbalance. The heat loss caused by the imbalance of the outer pipe network and the vertical imbalance of the heating system is considerable. The horizontal imbalance of the outer pipe network of the condensing boiler and the heat loss caused by the vertical misalignment of the indoor heating system are large. Therefore, in order to improve the efficiency of the condensing boiler, it is necessary to improve the efficiency of the pipe network transportation. Nowadays, the cost of energy is high, and it is very important to reduce the loss of heat loss in the condensing boiler network. In order to reduce the heat loss of the pipe network, the condensing boiler should adopt a hydraulic balance system and a room temperature control system.

The above is the principle of improving the efficiency of the condensing boiler summarized by FANGKUAI Boiler. In addition, the efficiency of each condensing boiler needs to be improved. For this reason, it is best to choose a proportional adjustment burner for the condensing boiler. At the same time, it is required that the commissioning work of the manufacturer must be standardized and in place, and based on the test report. Only in this way can the average operating efficiency of the boiler be close under normal load conditions. Rated efficiency.
