Embodiment Construction

[0086] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0087] The invention provides a method for detecting energy efficiency of a boiler, such as figure 1 As shown, the method includes the steps of:

[0088] Control the boiler to enter the heating stage, stable stage and cooling stage in turn and measure the boiler parameters in the heating stage, stable stage and cooling stage respectively;

[0089] Carry out energy efficiency detection on the boiler according to the boiler parameters in the heating stage, stable stage and cooling stage;

[0090] Wherein, the boiler parameters include boiler water supply temperature, circulating water flow, return water temperature and real-time power.

[0091] Specifically, before the control boiler enters the heating stage, the stable stage and the cooling stage successively and measures the boiler parameters of the heating stage, the stable s...

Abstract

The energy efficiency detecting method and device of a boiler are disclosed. The method comprises the following steps of carrying out a preliminary experiment on the boiler, starting the boiler, making a boiler water supply temperature in the boiler parameters of the boiler reach a first stable temperature value from a second stable temperature value and maintaining set measurement time; then closing the boiler to cool the boiler so that the boiler water supply temperature in the boiler parameters reaches the second stable temperature value; and determining the stable energy efficiency, a heatstorage capacity and average energy efficiency of the boiler according to the boiler parameters in heating, stabilizing and cooling stages. In the technical scheme, the water supply temperature or the energy efficiency of the stable operation state of the regenerative electric boiler of real-time power periodic fluctuation can be accurately measured, and simultaneously the effective heat storagecapacity of the electric boiler can be conveniently measured.

Description

technical field [0001] The invention relates to the field of energy efficiency evaluation of electric boilers, in particular to an energy efficiency detection method and device suitable for a boiler. Background technique [0002] With the intensification of atmospheric environmental pollution such as smog, my country has paid more and more attention to environmental pollution. To "promote clean heating in winter in the northern region", in accordance with the policy of enterprises as the mainstay, government promotion, and residents' affordability, gas should be used for gas, electricity should be used for electricity, clean energy should be used as much as possible, and the proportion of clean heating should be accelerated. [0003] In the clean heating technology, the electric boiler, as an important electric heating equipment, plays an important role in promoting the increase of the proportion of clean heating. With the rapid development of electric boiler technology, th...
