    • The object of the invention is to provide a boiler using coal, oil or gas as its fuel. This boiler is installed at an incline and has a plurality of grate pipes (16, 16a) containing water and arranged in the lower portion of the combustion chamber (20). The grate pipes (16, 16a) support lump coal in the combustion chamber. Thus improving thermal efficiency of the boiler. A fire pipe (14) axially extends within a water pipe (11, 11a) thereby forming a double-pipe structure. During operation of the boiler steam from the water pipes (11, 11a) passes through a reheating unit (44) installed in the combustion chamber (20). This boiler also has a cleaning unit for automatically removing sludge from the fire pipes (14). The boiler effectively uses lump coal which is inexpensive and has a high energy value, in addition to oil or gas as its fuel.
    • 本发明的目的是提供一种使用煤,油或气体作为其燃料的锅炉。 该锅炉安装在倾斜处,并且具有多个排放在燃烧室(20)下部的排水管(16,16a)。 炉排管道(16,16a)在燃烧室中支撑块煤。 从而提高锅炉的热效率。 火管(14)在水管(11,11a)内轴向延伸,从而形成双管结构。 在锅炉运行期间,来自水管(11,11a)的蒸汽通过安装在燃烧室(20)中的再加热单元(44)。 该锅炉还具有用于自动从消防管(14)除去污泥的清洁单元。 锅炉有效地使用廉价且具有高能量的块煤,除了以油或气为燃料。

    • 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.
    • 公开了一种煤,油,燃气锅炉系统。 在该系统中,水管布置在锅炉本体内,同时彼此进行表面接触,管道之间的间隙填充有耐火水泥,并将管道更牢固地锁定在一起。 因此,水管有效地抵抗了高的蒸汽和水压。 通过有效地向燃烧室内的燃料供给空气,同时通过二次空气在燃烧室内形成涡流,可以防止废气引起环境污染。 因此,该系统实现了燃烧效率的提高。 通过在每个水管中轴向布置的内部消防管,提高了系统的蒸发效果。 水管内的水如果在火管内被火焰快速加热。 脱硫装置在通过燃烧器燃烧废气的同时,在电除尘器的排气中注入粉状氢氧化钙。 废气也通过两个塔,其中向气体供应氢氧化钙,从而将气体的二氧化碳变成碳酸钙。 因此,该系统将没有有毒气体的废气排放到大气中。 该系统牢固地抵抗了极高的操作压力,提高燃烧效率,有效地产生可用的蒸汽,并且在排出废气中吸收去除其它有毒气体的同时对废气进行脱硫。
