Monitoring Emissions From Large Combustion Plants

Abstract

The most important aspect of the national environmental policy concerns air pollutant emission decrease. The studies led in order to identify the atmospheric pollution sources have revealed that the energy sector is one of the biggest pollutants in the economy. Given the negative impact of the pollutant emissions on the environment and the possibility of closing the large combustion plants in case necessary measures to comply with the legal regulations in the field are not taken will significantly reduce the amount of air pollutants from these installations. This paper presents a case study regarding the monitoring of emissions from the large combustion plants on the platform of S.C. CET S.A. in Bacau.

Monitoring the Particulate Matter (PM10) Emissions from Bacau City Termo-Energetic Industry

“…The central heating and power plant of type 1 has the mission of providing public service with heating supply for the inhabitants in Bacau according to the required quality parameters, with a nominal horse power/rated output of 419 MWt, with two large combustion plants, including auxiliary installations [12,19,20]:…”

“…The chimney has the role to ensure the dispersion of the gas into the atmosphere and is sized so as not to achieve the admissible concentration limit values for the pollutants emitted into the atmosphere. The gases that result from the combustion processes of coal (lignite) in the thermal energy reservoir of 420 t/h contain a large amount of ash (70g/Nm 3 ), for which, the electric plant has been designed with a retaining system of solid powders in suspension within the fume discharged through the creel/chimney [12,19]. Bacau Electro-thermal plant has a compliance period as stipulated by the GD 440/2010 concerning the emission limit allowed for dust (Table 1) as required by the Council Directive no.…”

“…Bacau Electro-thermal plant has a compliance period as stipulated by the GD 440/2010 concerning the emission limit allowed for dust (Table 1) as required by the Council Directive no. 2001/80/CE on the limitation of certain pollutants emission into the air from large combustion plants, as in the Commitment resulted from the negotiation process in Chaper 22 -Environment (MA, 2006) [12,19]. Until compliance, the combustion plant is allowed to function provided the annual limit emissions negotiated are respected (MA, 2006).…”

“…The present paper analyses the measurements carried out during November 2010 and March 2011, a period in which the boiler had a normal functioning. The main scope of the measurements has been to determine the dust emissions values [12,19].…”

“…The eudiometer DELTA 2000CD IV has been used as a measuring machine. Figures 1 and 2 emphasize the way the measurement points were located in order to determine the dust emission values for the CRG 1870 type of boiler [12,19].…”
