<p>A coal, oil and gas-fired boiler system is disclosed. In the system, water pipes are arranged within a boiler body while being brought into surface-contact with each other, with the gaps between the pipes being filled with refractory cement and more firmly locking the pipes together. The water pipes thus effectively resist high steam and water pressures. The exhaust gas is prevented from causing environmental pollution by effectively supplying air to fuel within the combustion chamber, while forming a vortex within the combustion chamber by secondary air. The system thus achieves improved combustion efficiency. The vaporization effect of the system is improved by internal fire pipes axially arranged within each water pipe. Water within the water pipes if thus quickly heated by the flame within the fire pipes. A desulfurization unit injects powdered calcium hydroxide to the exhaust gas at an electric dust collector while burning the exhaust gas by a burner. The exhaust gas also passes through two towers wherein calcium hydroxide is supplied to the gas, thus changing carbon dioxide of the gas into calcium carbonate. The system thus discharges exhaust gas free from toxic gases into the atmosphere. The system firmly resists an exceedingly high operational pressure, improves combustion efficiency, effectively generates usable steam, and desulfurizing exhaust gas while absorption-removing other toxic gases from the exhaust gas.</p> |
