fired coal hot water boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
The coal hot water boilers from Keystoker make for a powerful heating option to use in your home, or commercial building. Using anthracite coal to burn, or oil if you purchase a dual fuel kit, this coal burning boiler can produce anywhere from 85,000 to 528,000 BTUs.
It looks after all your hot water needs and also the elements in your hot water heating unit may never start up again! Safety. Our heating system is made to be located away from your home, in the yard. The normal range is about 50 to 100 feet. An outside coal boiler will remove the risk of stove fires in the house.
DZH Moving Grate Coal Fired Hot Water Boilers is suitable for wood chips, wood brick, wood pellet and coal as fuel. It is one dual fuel boiler and do not have strict requirement for fuel size. DZH moving grate coal fired boiler is widely used in smaller steam capacity requirement. Feature of CDZH Moving Grate Coal Fired Hot Water Boilers
Keystoker Coal-Fired Boiler. Coal furnaces are designed for ease of installation and easy access for servicing ; Available B.T.U. ratings per hr. from 85,000 to 528,000; Dual fuel coal and oil boilers available; Supply all domestic hot water for bath and kitchen use, in addition to heating the home
COAL FIRED BOILERS Hurst Boiler and Welding Co., Inc. provides its clients with the support and expertise necessary to design, fabricate and install complete coal fired boiler systems from the fuel storage system thru exhaust gas emission mitigation.
SZL series vertical dual drums chain grate water tube hot water boiler, adopts quick fitting and assembly structure. The 4-6t/h boiler is of quick fitting tube structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components.
Domestic heating coal fired hot water boilers are widely used in north of China, Mongolia and Russia. Coal is the cheapest fuel for domestic heating. The installation of doemstic heating coal fired hot water boiler is also very easy.
Our engineers developed an automatic stoker unit equipped with a coal hopper that held enough fuel for several days. This allowed the coal to be cleanly burned and without frequent maintenance. They then saw the need to make a hot water boiler specifically designed to burn coal and built them in multiple sizes to meet our customers’ needs.
