System and method for on-line monitoring energy consumption cost of spiral feeding type small-sized steam boiler

Abstract

The invention discloses a system and a method for monitoring energy consumption cost of a spiral feeding type small-sized steam boiler on line, which can acquire energy consumption and cost data of the boiler in time, accurately calculate single-circle energy consumption cost and unit steam energy consumption cost and provide a basis for the improvement on the average operating efficiency of the boiler so as to achieve an energy-saving effect. In the system, a steam flow instrument, a fuel using amount monitoring device, an electricity meter and a water power flow instrument are in communication connection with a computer, so that the energy consumption cost of the boiler can be conveniently measured; the energy consumption cost is reduced to the lowest limit by reasonably adjusting the operating condition and the fuel of the boiler through the energy consumption and cost data which is monitored in real time by the system; simultaneously, all parameters are monitored on line, data acquisition and calculation processes are finished by the computer, and the authenticity of the data is reflected; and the on-line monitoring method provides in-time and accurate energy consumption data and technical indexes for the operation of the boiler.

Description

technical field [0001] The invention relates to an online monitoring system and method for energy consumption cost of a screw-feeding small steam boiler. Background technique [0002] At present, there are more than 1 million industrial boilers in use in the country, with an average capacity of about 10 t / h, most of which are small boilers with a capacity of less than 20 t / h, and the average operating efficiency of the boilers is only 45%-65% compared with foreign advanced levels 15-20 percentage points lower. The low efficiency causes serious energy waste. In order to improve the efficiency of the boiler, the data on the energy consumption and cost of the boiler should be relatively clear first, and then the corresponding adjustment can be made according to the reasons of data analysis. Therefore, the detection of the energy consumption and cost of the boiler is the premise . [0003] For the detection of energy consumption and cost, there are few domestic researches at p...

AI Technical Summary

Problems solved by technology

At present, the fuel consumption of industrial boilers is generally measured by electronic belt scales, but it can only measure the amount of fuel entering the silo in front of the furnace, and cannot prepare to express the instantaneous or short-term fuel consumption of the boiler, which is not conducive to the monitoring of energy consumption costs
