Young fire layer combustion longitudinal drum boiler steps: 1. open-air boiler exhaust valves, control drum water level. 2. Start to coal to the furnace a small amount of coal. 3. Start fan, a fan, to adjust an amount of wind, an amount slightly above the minimum fluidization, the bed temperature was raised to 850 deg.] C when appropriate to increase the amount of wind. 4. When the bed temperature was raised to 600 ℃, stoker bed temperature rise should not cause stoker stop, this time because the material layer may be let go Her Majesty portion of the bed material, according to the operation method for starting the ignition furnace. When the boiler shutdown maintenance, cooling by any rules?
During installation, the technical team fast layer combustion longitudinal drum boiler plant according to the specific needs of our environment, our rational arrangement of stacks, pipes, and other auxiliary equipment, let us bring a lot of convenience in the latter part of the course. Fang fast responsible attitude also gives us impressed, sent a technical team for installation, commissioning and training to us, let us rest assured, peace of mind, peace of mind. --customer feedback
The change of layer combustion longitudinal drum boiler water level can make steam pressure unstable, even full water or lack of water accident. Therefore, in order to keep the water level fluctuating slightly near the normal water level, the boiler should supply water evenly and continuously as far as possible in order to keep the water level fluctuating slightly near the normal water level. If low water level appears, the combustion should be controlled immediately. All kinds of boilers with different structures have prescribed the minimum safe water level, which must be maintained above the minimum water level limit in the operation of the boiler. The above is manual regulation, small-sized fuel-fired gas-fired boilers are generally automatic regulation.
Users purchase their own needs or may be advantageously combined conditions are selected. On selecting the style is simpler, suitable for horizontal or vertical, provided that they meet the requirements placed layer combustion longitudinal drum boiler to boiler room.
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler. The fundamental characteristic of the "three-drum" design is the arrangement of a steam drum above two water drums, in a triangular layout. Water tubes fill in the two sides of thisLearn More
The drums of bi-drum boilers can be anywhere near 100 tons. The boiler drums have large stubs welded, many instrument tapings, safety valve stubs, and internals to maintain the quality of steam and distribute the feed wate, and a facility to dose the chemicals uniformly across the length of the drum. Boiler drums are generally made of carbonLearn More
Boilers in power plants and process plants have large drums to house the steam-water mixture, to hold large quantity of water required for steam generation, and ensure steam quality. Drums weigh anywhere 100 to 250 tons with very high thickness. Manufacturing drums need special machines and process. slide 1 of 3.Learn More

Box headers are fastened directly to the drum when the drum is inclined. When the drum is horizontal, the front box header is connected to it at an angle greater than 90 degrees. The rear box header is connected to the drum by tubes. Longitudinal or cross baffles can be used with either type. Bent Tube . Bent tube boilers usually have three drums. The drums are usually of the same diameter and positioned at different levels with each other.Learn More
