The invention relates to a coating, and provides an expanding type steel structure fireproof and anticorrosion coating which integrates an anticorrosion coating layer and a fireproof coating layer. The utility model also provides a preparation method of the expanding type steel structure fireproof and anticorrosion coating. The raw material components comprise montmorillonite, FeCI3.6H2O, pyrrole or aniline, sodium dodecyl benzene sulfonate, surface treatment agent, dispersing agent, base resin, plasticizing agent, dehydrating and char-forming catalyst, char-forming agent, foaming agent pigment and filler, anticorrosion filler, flow agent and film forming additive. Waterborne silicone-acrylate resin and hydroxyl acrylic resin serve as the base resin to replace traditional oleoresin, thereby achieving zero VOC (volatile organic compound) discharge; a nanometer montmorillonite and conducting polymer composite material with an intercalated structure is utilized as conducting filler, so that the coating has excellent anticorrosion performance; and meanwhile, an ultrathin expanding type fireproof component is added, and the ratio of the compound components is collaboratively optimized, thereby solving the problems that the compatibility between the two layers is poor and the layers are easy to fall off, and reducing the cost.

The invention discloses a composite startup burner for a powder coal gasification furnace. The composite startup burner comprises an inner burner and an outer burner which are provided with a front necking end respectively and are coaxially sleeved from the inside to the outside, wherein a cooling water jacket adopting a single-spin mode is arranged on the periphery of the outer wall of the outerburner; the front end of the inner burner is provided with an ignition electrode; and the nozzle of the burner is provided with a supersonic atomization device. The composite startup burner adopts supersonic atomization to ensure that the burner has small fluctuations in fuel and atomization airflow rate, and a little change in outlet speed in a process that the back pressure rises continuously so as to ensure the atomization effect and high-temperature flame far from the head of the burner; the composite startup burner adopts a center ignition mode to save an ignition burner to realize the two-in-one function, and adopts a single-spin cooling mode to ensure that the head of the burner is protected from damage under the condition of high temperature and high pressure to prolong the service life of the burner.
