DZH coal fired moving grate steam boiler is single drum boiler with both water tube and fire tube, the combustion equipment is moving grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and spirally corrugated tubes in the drum are convection heating area. This coal fired moving grate boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The furnace structure is in reasonable arrangement to achieve high efficiency. This moving grate boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.

Main features of coal fired steam boiler:

Performance advantage

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 protection

biomass 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.

Safety protection

Boiler steam pressure automatic adjustment system: The control system of the boiler steam pressure automatic adjustment system enters the working state. When the necessary conditions for combustion are met: the steam pressure in the boiler is higher than or equal to the set pressure upper limit, the control system outputs a stop signal. Until the induced draft fan is stopped.

Water supply automatic control: When the system is on duty and in normal operation, the water supply pump is started, and the water level differential pressure transmitter detects the water level signal to keep the water level of the drum stable. Ensure the quality of steam. The water level adjustment instrument displays the boiler water level.

Manual control: You can also manually control the water pump, etc. through the manual touch key on the control panel.

DZH series fixed grate biomass steam boiler is widely used in hospitals, schools, textile mills, garment factories, large supermarkets, garment factories, dyeing factory, hotel, dining room, restaurant, food factory, beverage factory, soy products, meat products factory, cannery, brewery, pharmaceutical factory, packaging plant, building materials factory, paint factory, swimming pool and other places of the enterprises and institutions.
