Steam Blowing - EnggCyclopedia

Purpose of steam blowing. Cleaning by steam blowing is carried out essentially for steam circuits (i.e for steam generating boilers, steam heated exchangers, steam turbine upstream piping or other steam lines).Due to problems of condensation of steam or draining of condensate, this type of cleaning has to be used with the utmost care, as it can potentially create vacuum in the equipments being

Steam blowing - Constructed items general discussion

2002-12-24 · Steam blowing usually takes place with pressures lower than rated pressure so disturbance factor more correctly includes the effect of steam density on the "cleaning force" for want of a better term. The other advantage of using disturbance factor is that there is no need to measure the steam flow and take the risk of damaging the flow nozzle

Challenges to Combined-Cycle Plant Steam Blowing

2018-9-10 · Combined cycle plants using gas and steam turbines in parallel present a special set of challenges during cleaning. Any missed debris can cause millions of dollars of damage to the steam turbine if the procedure is performed incorrectly, and variances in pressure tolerance between a steam and gas turbine often mean steam blowing must be done in sections.

Combined Cycle Plant Steam Blow Overview

Typically, a combined-cycle power plant comprises of gas turbine generators fitted with either a Once Through Steam Generator (OTSG) or a Heat Recovery Steam Generator (HRSG) and Steam Turbine(s). Water is run through an OTSG or a HRSG that captures exhaust heat from the gas turbine that would otherwise escape through the exhaust stack.

Water is run through an OTSG or a HRSG that captures exhaust heat from the gas turbine that would otherwise escape through the exhaust stack. To facilitate the water requirements for steam blowing, a temporary water source with boiler feed water quality will likely . Get A

Boiler Pipelines Steam Blowing Procedure: Why and

2020-10-15 · Any impurity being dislodged from the boiler or steam pipes during operation of the power plant can lead to a major damage in the turbine, and so the steam boiler and their associated pipes need to be cleaned before rolling the turbine for the fist time. After that the procedure is done regularly to keep the system clean. Steam blowing procedures are used to clean the boiler system and pipe lines.

The steam blow of HP-, RH-System and common steam lines within 2 days of effective steam blowing. Paper for International Conference POWER PLANTS 2014 Zlatibor Serbia, October 28th-31st. Operational cleaning and steam blow of large Thermal Power Plant boilers (Kostolac B2

Steam Blowing Procedure | Steam Blow Out Services

2018-9-15 · Steam Blowing Procedure. Steam blowing is one of the initial stages of start-up operation. It uses a high drag force on the surface of your piping to remove and capture debris from your system. There are two types of steam blowing — the puffing method and the continuous blowing method. At ESI, we provide high-velocity steam blowing and steam

Steam Blowing of Supercritical Thermal Power Plant

2016-10-28 · study on steam blowing and its parameter is carried out. 1.3 Plant details:The steam generator is a once through super critical type (ALSTOM MAKE BOILER). The circuit which are subjected to steam blowing are super heater section of boiler, main steam line up to HP turbine, cold re-heater, hot re-heater line up to IP turbine, HP and LP by pass line.

Steam Blowing - Effective in the removal of debris

Typically, boiler pressures used in steam blowing provide a dynamic pressure throughout the piping that is at least 20% higher than would be experienced in normal operating conditions (CFR ≥ 1.2). Any potentially damaging particles will be blown out of the piping prior to plant operation.
