Many friends want to know how to save the running cost of gas boilers. In fact, gas boilers can save more than 15% of energy in the following 5 points. The rated evaporation capacity or power and the number of gas-saving boilers are reasonably selected according to the steam demand of industrial production. The purpose of energy saving of natural gas steam gas boilers is to improve the feed water temperature of deaerated water by setting a heat exchanger, and to utilize the heat continuously discharged and periodically discharged from the water.

Energy-saving boiler

  1. Reasonable selection.

  The rated evaporation capacity or power of the gas boiler and the number of energy-saving boilers should be reasonably selected according to the amount of steam required for industrial production. The closer these two match actual usage, the smaller the flue gas loss, and the more obvious the energy saving.

  2. Reasonable air-fuel ratio.

  In order to improve the combustion efficiency of the fuel and reduce the emission of polluting gases, achieving the goal of double energy saving, a suitable burner should be selected to make the proportion of fuel and air appropriate.

  3. Reduce flue gas temperature.

  In order to reduce the flue gas temperature of the energy-saving boiler and effectively utilize the waste heat generated in the flue gas, the efficiency of commonly used boilers is 88-92%, and the flue gas temperature is 140-180℃. Energy savers and condensers are installed at the tail end of the boiler for two-stage waste heat recovery. If energy savers and condensers are installed, after using the waste heat from the flue gas, the flue gas temperature is reduced to 60-120℃, and the boiler efficiency can be increased to 96-99%.

  4. Recycling of waste water heat.

  Natural gas steam gasEnergy-saving boilerThe purpose is to improve the feed water temperature of deaerated water by setting a heat exchanger and utilize the heat of continuous and periodic discharge of water.

  5. Recovery of condensate heat.

  In order to achieve energy saving, a condensate recovery device can be set up to fully utilize the heat of the condensate and effectively recover the waste heat of the condensate. At the same time, because the water quality of the condensate is good, it can be directly supplied to the gas energy-saving boiler without treatment, and the purpose of saving water and energy can also be achieved.

  It has strong data storage, analysis and calculation capabilities, and can systematically analyze the operation of the boiler system within a certain period of time, which is convenient for energy saving analysis and statistics.

  However, the energy-saving diagnosis of this system requires adjusting the boiler's operation status with the cooperation of the boiler. In order to achieve the purpose of energy-saving operation, the boiler's operation is not adjusted completely automatically and intelligently according to the diagnosis results by computer.

  Energy-saving boilerVarious parameters of the diagnosis can be obtained by collecting and analyzing and processing the online thermal data of coal-fired industrial boilers. Whether the boiler operating parameters are abnormal can be determined by analyzing the magnitude of each heat loss and comparing it with normal conditions. In case of abnormality, a warning should be issued in the form of an audio-visual alarm, and the boiler management personnel should promptly perform corresponding operations according to the system's suggestions to make the boiler save energy and operate economically.

  Integrating on-site energy efficiency data collection, on-site test analysis, and online calculation, it is not only an energy efficiency test for a certain working condition, but also monitors the boiler's real-time working conditions, and can perform energy-saving diagnosis on the boiler all day long. It has the characteristics of fewer energy efficiency testers, short time, high efficiency, and accurate test results.

  The above is to help friends understand the energy saving of gas boilers.
