Coal-fired steam boiler shell boiler, combustion equipment for the chain grate. The coal fired boiler price is reasonable. The water cooling walls on the left and right sides of the furnace are radiant heating surfaces, and the two wings of the furnace are convection heating surfaces. The tube is arranged in the convective heating surface of threaded smoke pipe, the front and back arches are made of heat-resistant concrete with a new technology of integral pouring and ramming, and the outer side of the boiler main engine is a three-dimensional protective plate shell.
The fuel of 4Ton coal-fired steam boiler falls from the coal scuttle to the front of the grate. With the operation of the grate, the coal is preheated and retorted, ignited and burned up, and the slag falls into the slag bucket. By the slag eliminator at any time, the flue gas in the throat between the front and back arches can form eddy current and air fully mixed, and heat the front arch, improve the ignition conditions, through the upper exit of the arch into the convective bundle of the two wings, through the front smoke box into the threaded smoke pipe, through the economizer, dust collector, from the induced draft fan to the chimney discharge.
The coal fired boiler price is reasonable, the boiler structure is compact, compared with the same type of boiler, the external size is small, and the investment of boiler house is saved. This series of boiler products are composed of arch tube-sheet and threaded smoke tube, which makes the cylinder change from quasi-rigid body to quasi-elastic body structure, and cances the tube-sheet area and reduces the stress. The smoke pipe is changed from two return to single return, which solves the problem of tube plate crack. The lower part of the steam boiler drum is arranged with a rising pipe row, which eliminates the dead water area at the bottom of the drum, so that the sludge is not easy to deposit, the high temperature area of the drum can be well cooled, and the lower part of the boiler shell can be prevented from bulging.
This series of boilers adopts high efficiency heat transfer threaded smoke tube, which can enhance heat transfer effect, achieve the characteristics of boiler temperature rise and pressure boost quickly, and improve the thermal efficiency of the boiler. The boiler strengthens heat transfer through the threaded pipe, improves the heat transfer coefficient and thermal efficiency, because the flue gas has the disturbance effect in the pipe, the pipe is not easy to accumulate ash, play the role of self-cleaning. At the same time, high efficiency and energy saving furnace arch of heat-resistant concrete casting is used in the furnace to improve the coal ignition conditions, and an independent air chamber is used to achieve reasonable air distribution, so that an aerodynamic field conducive to combustion is formed in the furnace, thus expanding the adaptability of coal.
The coal fired boiler price is reasonable, the overall operation of the boiler is stable, and the adjustment is convenient. The secondary air is arranged at the arch throat of the series steam boiler furnace, which can effectively organize the volatile fuel and air mixing, promote the volatiles to fully burn in the furnace, and improve the fuel burnout efficiency. The furnace arch and outlet smoke window of the boiler have a certain dust removal function. The original dust concentration of the boiler is controlled below the standard to ensure that the dust emission of the boiler meets the environmental protection requirements.
