Vertical steam boiler introduce vertical steam boiler Products: vertical steam boiler, all kinds of domestic furnaces comprehensive technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product has been designed applied for the patent, the boiler head boiler shell, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney. Performance: the boiler furnace grate rests within an upper portion of the U-shaped scraps, the direct flame furnace, and flushing mounted within curved tube furnace; vertical bent tube boiler structural features are: furnace interior curved inner pipe, increase radiation heating area. However, due to large water-cooling degree furnace, the furnace temperature reduced accordingly, therefore, generally suitable for burning high quality coal. The increase in the furnace masonry bricks, to maintain a high temperature furnace burn less coal. Better water circulation, where the site has been washed flue gas cooling water, the whole structure, good elasticity. Features: use of double grate combustion section of the combustion chamber, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust effect. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal.

Preparation before the coal fired hot water boiler with quality protection hot water boiler is enabled prior to use, fully prepared to do so that the hot water boiler can be carried out smoothly at the time of use. So before using hot water boiler what to do to prepare it. Hot water boiler with preparation before the fire. Hot water boiler before Stoke shall check the following: First, check the boiler (including combustion grate, reducer, economizer, pressure gauges, thermometers, valve, exhaust valve, drain valve, return water valve, check valve, etc.) and ancillary equipment (including blowers, dust, coal, dust, water softener, pumps, motors, decontamination, expansion tank and controlled instruments, etc.) does meet the requirements, to achieve complete, accurate, sensitive and reliable. Second, the combustion apparatus where inspection is intact. Third, when the equipment inspection and approval, prior to closing the boiler manhole and hand hole, should identify the boiler, when the combustion chamber before the smoke and debris before they closed and no one did. Fourth, when the water heating system all To open the exhaust valve, the discharge cold air, until the water is full closed. Fifth, before Stoke boiler, boiler combustion chamber and flue deal with the implementation of ventilation. Should natural ventilation and boiler flue door opening 9; 16 minutes, the mechanical ventilation of a boiler, induced draft fan starts to be less than 6 minutes. When the sixth water, check the boiler economizer and the hand hole cover, whether Flange water leakage, water leakage should be found processing. Seventh, ancillary equipment lubricated part of the boiler should be filled with oil. These are said to be done before the hot water boiler in preparation we want to help.

Mar 03, 2008 · I have recently purchased a house with a coal fired back boiler that heats the water and the central heating. The heating is on demand via a simple on/off switch on the wall which gets red hot. The water on the other hand will not run hot out of the taps even though i can here it bubbling and have to put the radiators on to disperse some heat.Online chat
