Application:used for all kinds of industrial production and processing.7. Standard of Design, Manufacturing and Inspection: GB150Application:Textile Mill,Food and Beverage,Chemical,Medicine,Light Industry,Rubber,Printing and Dyeing Plant,Paper Mill,Wood Processing,Garment and Laundry etc.DZH type steam boiler body for the "A" structure, uniform heating surface, and the use of A certain radian, elastic, easy to expand and shrink the water wall pipe and strengthen the heat transfer of the screw pipe smoke pipe, the maximum to ensure the safety and efficiency.The pot shell, tube plate and other pressurized parts are elastic or quasi-elastic, which can improve the stress state to the greatest extent.The wing-shaped flue structure is adopted on both sides of the pot shell, which can effectively reduce the heat deviation of the system and ensure the heat transfer of the system is efficient and stable.The lower part of the boiler body is provided with an ascending tube, and there is no stagnant water in the pot, which can effectively solve the overburning and bulging at the bottom of the pot shell.The system itself has a certain self-dedusting ability to meet the increasingly stringent environmental requirements.DZH series boiler is manual operation biomass steam boiler which adopting manual fuel feeding, manual slag removing. The fuel can be firewood, wood logs, biomass pellets, peanuts shell, grain shell, etc. Equipped with special dust collector solution (water film dust collector, bag type static electricity dust collector, double towers desulfurization, etc.), it can realize automatic fuel feeding, automatic ash removing. It is the most popular products in Southeast Asia, Central Asia, Africa.Product Parameters

Technical Advantage
Main features of coal fired steam boiler
1. The steam boiler is the horizontal quick-loading boiler with natural circulation of working medium.The boiler heat exchange system is composed of a boiler barrel, a set box and a water cooling wall. The main heating surface is composed of a furnace water cooling wall, part of the boiler barrel and a convection tube bundle inside the boiler barrel.2. Advanced design performance:The main heating surface tube of the boiler is made of seamless steel tube of no. 20 low and medium pressure boiler, and the boiler barrel is made of special steel plate for the boiler.The left and right containers are made of seamless steel tubes.3. The boiler arch is made of fire-resistant concrete.The rear arch is low and long, so it burns well. The wings of the flue and the side wall tiles are made of refractory sintered bricks.Boiler front wall and back wall adopt universal firebrick.4. Reasonable exhaust ventilation, large combustion chamber and strong applicability of coal.Suitable for all kinds of bituminous coal or anthracite, mixed coal.Well burned.Because the high-temperature flue gas first enters the settlement chamber, and then from both sides enters the two wings of the flue and the front smoke box, so the effect of smoke removal and dust removal is good.5. Simple water circulation, reasonable structure of pressurized parts, and safe operation under the condition of ensuring water quality.6. The combustion equipment is a fast-loading grate, which can be manufactured and installed in the factory and directly installed on the foundation after being transported to the site.With reasonable structure, compact, low steel consumption, so that the boiler performance, weight, structure and size compared with domestic products with the same capacity has obvious advanced.7. Energy saving and environmental protectionbiomass steam boiler adopt the latest gasification combustion technology, set up the advanced gasification rotary combustor, built-in cyclone secondary air distribution, make fuel combustion more full.8, and the use of efficient heat transfer elements - threaded smoke pipe, with a reasonable flow of flue gas, so that the boiler thermal efficiency is higher.The thermal efficiency is over 85%.9. The steam boiler adopts the green renewable biomass lignin pellet fuel promoted by the state, with zero CO2 emission, smoke emission concentration less than 50mg/m3, smoke blackness less than Ringerman I class, and all indicators meet the national environmental protection standards of the first class.10. Low operating cost: The fuel lignin biomass pellet used by the boiler is a new type of environmental protection fuel supported and promoted by the state. It is a renewable resource.It has the characteristics of high calorific value, low cost and wide source.Its operating costs are only a quarter of those of electric boilers and less than half of those of oil-fired (gas-fired) steam boilers.11, high degree of automation: digital integrated controller, according to the user can set the automatic controller burning conditions, simple and convenient operation, automatic ignition, automatic feeding, automatic ash cleaning, gas boiler operation is equally convenient.Scope of application for biomass steam boiler
Coal fired steam boiler is suitable for painting room, drying box, drying tower painting line and other purposes.It is especially suitable for central heating in urban residential areas, industrial production, enterprises and institutions, schools, hotels, bath centers and other places where heating, hot water and steam are needed.
the maintenance of steam boilerFault alarm and protection
The control system can monitor the current working conditions of the steam boiler in real time and carry out real-time and comprehensive intelligent fault identification and treatment.The control system can diagnose and deal with the following faults in real time:
Extremely high steam pressure protection: when the steam in the pot is overpressure, the control system will immediately enter the chain, and sound and light alarm, screen display;The steam pressure is extremely high.After the fault is eliminated, press the reset button to break the chain.
Protection of water shortage in boiler: in case of extremely low water level failure due to pump failure or other reasons, the control system will immediately shut down the power supply of induced draft fan, enter the chain, and alarm with sound and light, and the screen will show extremely low water level.After the fault is eliminated, press the reset button to break the chain.
Ultra high boiler water level: when the water level in the pot is higher than the upper warning level, sound and light alarm will be given.Prompt the high limit of water level in the pot, the display screen prompt drainage.Automatic recovery after the fault is eliminated, stop the pump without stopping the furnace.
Water pump motor overload: heat relay action when water pump motor overflows, cut off the power supply of water pump motor and stop water pump, realized by hardware.
Power failure: In case of power failure, the control system will immediately shut down the power supply of all equipment in the cabinet.When the power is restored, the cabinet will be in the off-duty state automatically. It is necessary to restart the machine and start the equipment to ensure the safety of the equipment.
