Resumo

A planta siderúrgica da TKCSA possui em seu sistema de distribuição de gás dois flares (bleeders) que possuem funções distintas durante o regime normal de operação. O flare 2 é responsável por queimar o gás de alto forno de baixo poder calorífico, gerado no início do processo de partida do alto-forno até que o gás atinja as características adequadas para o aproveitamento e ser direcionado para o gasômetro. Já o flare 1 trabalha em conjunto com o gasômetro no processo de controle de pressão e vazão excedente de gás, quando da redução intempestiva de consumo de gás de alto forno. O presente trabalho apresenta a solução implantada pela TKCSA para garantir, sob quaisquer condições de fornecimento de energia elétrica, a operação dos equipamentos elétricos e de todo o sistema de automação e controle operacional dos flares. Podemos dizer que a operação do flares torna-se autônoma e relação ao sistema elétrico e sistema de automação e controle da distribuição de gás de alto forno. O sistema implantado promoveu uma elevação na segurança operacional dos flares, já que, a autonomia operacional impede o apagamento da chama eliminado a possibilidade de lançamento de gás cru na atmosfera.

 

The steel plant TKCSA has in its gas distribution system two flares (bleeders) that have distinct functions during normal operation conditions. The flare 2 is responsible for the start up of blast furnace when the gas of low calorific value, generated at the beginning of the process starting from the blast furnace until the gas reaches the appropriate characteristics for use and be directed to the flare. The flare 1 is in line with the gas system gasholder in control process pressure and excess gas flow when the untimely reduce consumption of blast furnace gas. This paper presents the solution implemented by CSA to ensure, under all conditions of supply of electricity, operation of electrical equipment and system-wide automation and operational control of flares. We can say that the operation of flares becomes autonomous and relationship to the electrical system and automation control and distribution of blast furnace gas system. The system deployed promoted an increase in operational safety flares since the operational autonomy prevents shutdown of the flame and blocking the possibility of release of raw gas in the atmosphere.

Whoops, looks like something went wrong.
