quality of boiler steam power plants pdf

When the user selects an electric heating quality of boiler steam power plants pdf, the eyes had better polish. Fast boiler teach you how to distinguish good and bad boiler insulation layer.

1, electric heating boiler pressure gauge (pressure transmitter) installation site should meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, while maintenance and easy to observe. Pressure must be laid high temperature medium pipe insulation, so as not to jeopardize the safety of the operator when the red tube.

2, take the pressure line must be fitted with a needle valve (operation pressure measuring line for shutting off the defective pressure), the second needle valve (administered with instrumentation, to stop using replacement), and the condensing coil elbow (elastic spacer element from the high-temperature heating medium, and facilitates the installation of encapsulant sheet) and discharge valves and outfall Road. For special pressure measurement, pressure line must also be taken to install the purge valve, isolation between.

The Fangkuai Group's unique full-operating quality of boiler steam power plants pdf operation laboratory has an annual operating cost of more than 5 million yuan, which can simulate the operating conditions of various types of boilers under multi-operating environment conditions. The laboratory provides technical tests such as test and inspection, analysis and evaluation, data evaluation, energy saving and environmental protection, and special software from materials to complete equipment, hardware to software, and even complex large systems.

Nitrogen oxides are classified into fuel type, heat type and rapid type according to the formation mechanism. The fuel type is generated by an oxidation reaction of nitrogen inherent in the fuel itself, and the heat type is combustion in which nitrogen in the air is oxidized at a high temperature, and rapid NOx generation is less. Understand the principle of nitrogen oxide formation in quality of boiler steam power plants pdf operation, and we can start to reduce the formation of nitrogen oxides from these aspects.

Why Adjustment To adjust the water level in the quality of boiler steam power plants pdf water level of the boiler? Generally, this is in order to maintain stable boiler drum (drum) water level, water level and step adjustments is: 1) to control the water level, water level must be carefully monitored, in principle, subject to a water level gauge, electrical The main point is to monitor water level meter. To maintain the water level in place clear and accurate. If the water level gauge mica or no rocked slightly unclear, flush water level indicator, each control level gauge regularly and accurately determine the change in water level the boiler; 2) always monitor the steam flow, feedwater flow, drum pressure and water pressure, and other major data is not normally found immediately identify the reasons, timely treatment; 3) + If the water level exceeds 50 mm, the small water supply damper should be closed to reduce the amount of water, if continued to rise to + 75 mm, the door should be open drainage accident turn on the water to normal water level, and investigate the cause.

Application Note: Monitoring Steam Purity in Power Plants

Plants with drum-type steam generators both conventional boilers and heat recovery steam generators (HRSGs) maintain steam purity by taking advantage of the physical separation that occurs between water and steam in the drum. As the water boils, it forms a steam-water mixture, which upon entering the drum separates into steam and water.
