Steam boiler superheater with a sectioned LIVE STEAM AND GAS REGULATION OF AUTOMATIC STEAM uniform heating in the sections SUCH Superheater

摘要

The invention relates to a power system. Achieves the results of the utility model is to increase the efficiency and reliability of the steam boiler by means of automatic regulation of the gas using a burner to ensure uniformity of heating steam in the superheater sections packets. According to the utility model, all packets with at least superheater acute boiler steam are divided into the same number of sections in the furnace and the flue boiler allocated respectively the width of the sections of the gas regulation zone and burner furnace walls of the boiler are arranged in groups of specified areas, each group of burners It is provided with an independent fuel and air supply system. Wherein at least one of the packets steam superheater adjusts stage, within which there are temperature sensors of the automatic regulation of the gas uniform heating steam superheater sections in a package. Said system according to the utility model comprises a separate for each zone of the gas regulating meter difference between the temperatures of steam in the outlet and the inlet of the mixing devices (collectors) of each section of the control stage, driver signal proportional to the average for the whole control stage value changes in temperature of steam in each section thereof, separate for each regulation zone of the gas generator of the main signal proportional to the difference between the actual value of said CONTINUE? and temperature for the respective control stage section and the average value of said differences, for each separate gas regulation correcting signal generator zone, the proportional rate of change corresponding to the main signal, as well as a separate regulation for each zone of a steam heating uniformity controller superheater sections in a package. 2 bp f ly-4-yl.
