Testing stand for thermal balancing test of boiler

Abstract

The invention, which belongs to the teaching apparatus field, relates to a testing stand for a thermal balancing test of a boiler. An objective of the invention is to design a testing stand for a thermal balancing test of a boiler, wherein the testing stand is used for collecting intelligently various load data generated under various circumstances of the boiler of a power plant. a concrete structure of the testing stand provided in the invention is arranged as follows: installing a gas fired-boiler on the testing stand, installing an air inlet pipe, an outlet pipe and an inlet pipe at a lower end of the gas fired-boiler, and installing a smoke exhaust pipe at an upper end of the gas fired-boiler; installing a water inlet thermometer, a gas flowmeter, a gas pressure meter, a water outlet thermometer, a water flowmeter, and a micro-differential pressure gauge of flue gas. arranging a measuring point of differential pressure and a measuring point of composition and temperature of flue gas on the smoke exhaust pipe; installing an air-inlet vortex flowmeter and a pressure transmitter on the air inlet pipe; installing a water-outlet temperature sensor on the outlet pipe; installing a water-inlet temperature sensor and a water-inlet turbine flowmeter on the inlet pipe; installing a sudden-stop switch on the testing stand; and arranging a working box at the lower end of the testing stand. The testing stand is invented for satisfying demands for culturing practice abilities of students and cultivating engineering applied talents; and therefore, a testing stand for a thermal balancing test of a boiler is developed and is used for making a comprehensive test of a thermal energy and power engineering major.

Description

technical field [0001] The invention belongs to the field of teaching instruments. Background technique [0002] Boiler heat balance experiment is an effective way to judge boiler design and operation, improve boiler economy, find out the main factors affecting boiler efficiency, and use it as a basis for improving boilers. Students can go to the power plant to do experiments, but due to safety issues and restrictions on the normal operation of the power plant, the power plant does not necessarily provide experimental conditions and opportunities. On the other hand, due to the complex structure and high operation requirements of this experimental equipment, the thermal energy and power engineering majors and architectural and environmental majors in major universities across the country have not set up this experiment, and there is no special boiler heat balance test bench for sale in the market.

Problems solved by technology

Students can go to the power plant to do experiments, but due to safety issues and restrictions on the normal operation of the power plant, the power plant does not necessarily provide experimental conditions and opportunities

On the other hand, due to the complex structure and high operation requirements of this experimental equipment, the thermal energy and power engineering majors and architectural and environmental majors in major universities across the country have not set up this experiment, and there is no special boiler heat balance test bench for sale in the market.

The teacher only talks about the principle of the boiler heat balance experiment in the lecture, and there is no way for the students to do the experiment by themselves. The students have no perceptual knowledge in this area, and the students' learning effect is not good.
