Abstract

The invention provides an adjustable pressurization system of serial-parallel boilers of big and small turbochargers, comprising a high-pressure stage turbine by-pass pipeline by-pass valve, a high-pressure stage turbine by-pass pipeline, a high-pressure stage turbine, a high-pressure and low-pressure turbine connection pipeline flow rate switching control valve, a high-pressure and low-pressure turbine connection pipeline, a low-pressure stage turbine by-pass pipeline, a low-pressure stage turbine, a steam output pipe system, a main steam turbine, a fume purification device, a high-pressure stage compressor by-pass pipeline by-pass valve, a high-pressure stage compressor by-pass pipeline, a high-pressure stage compressor, a high-pressure and low-pressure compressor connection pipeline flow rate switching control valve, a high-pressure and low-pressure compressor connection pipeline, a low-pressure stage compressor by-pass pipeline, an auxiliary steam turbine, a speed changing mechanism 1, a speed changing mechanism 2, a fuel oil supply system, a boiler water supply mechanism, an air conditioning baffle plate and a low-pressure stage compressor. The variation range of the equivalent weight circulation area of the turbine is wider, thereby the operation matching of a booster set and the boiler is improved and the purpose of optimizing the economy of the boiler is achieved.

Description

(1) Technical field [0001] The invention relates to an adjustable pressurization system for a boiler. In particular, it is a pressurization adjustment system suitable for use on a ship's pressurized boiler. (2) Background technology [0002] The main method to improve the economics of boiler installations is to increase the volumetric heat load of the boiler furnace or increase the heat absorption rate of the convective heating surface, and the only effective way to simultaneously increase the volumetric heat load of the boiler furnace and the heat absorption rate of the convective heating surface is to use a compressor instead of The steam turbine blower delivers combustion-supporting air to the boiler furnace, that is, air pressurization is used for the boiler. At present, most naval boilers use turbocharged units for air boosting, such as French Sura-type naval boilers and American naval natural water circulation booster boilers. For the main power equipment of the ship...
