DZL traveling grate boiler

Yongxing’s DZL series quick-installed Coal Fired Steam Boiler is horizontal three-pass water and fire tube chain grate boilers, which burn medium-quality bituminous coal.

The boiler body is a single drum longitudinally arranged, and the threaded pyrotechnic tube is arranged in the drum to form a convective heating surface.

The boiler drum and the water-cooled walls on both sides form the furnace radiation heating surface. The combustion equipment adopts a light chain grate.

DZL boiler is delivered in the form of integral quick installation. Electric control realizes step-less speed regulation of the grate, limit parameter alarm, and interlock protection.

DZL Automated Chain Grate Stoker Biomass Steam boilerDZL biomass steam boiler Coal Fired Steam Boiler Design features:

1. Which coal is used in steam boiler?

Coal Fired Steam Boiler Wide fuel adaptability: AII soft coal, anthracite, lignite, rice husk, sawdust, bagasse, molding biomass particles and direct-burning fuel, etc.

2. What is the efficiency of coal fired boilers?

Coal Fired Steam Boiler has high thermal efficiency.

The thermal efficiency is higher than that of similar coal boilers, the flue gas three-pass cycle, and the thermal efficiency is more than 80%.

We adopt threaded smoke pipe to improve the contact area and thermal efficiency, and the heat loss of exhaust smoke is small.

Using advanced arch design forms an inverted alpha flame, which improves combustion efficiency.

The use of membrane walls and water-cooled wall structure also dramatically improves thermal efficiency.

Our sufficient heating area helps you shallow heat loss.

3. Obvious design advantages.

The two-wing flue is arranged so that the flue gas can smoothly enter the front smokebox so that the temperature of the previous tube sheet is the same, and the tube sheet cracks caused by temperature stress are avoided.

The grate adopts a new type of small-scale grate piece, which adds a unique safety ring, making the grate run stably and reliably and improving combustion efficiency.

A dust collector is arranged in the tail flue to ensure that the smoke and dust discharge meets environmental protection requirements.

The boiler’s welding seam adopts advanced submerged arc automatic welding technology to ensure the welding quality.

With excellent drum and pipe design, Yongxing industrial steam boiler could expand upward freely. In this way, the boiler can stretch well and ensure it works for your long life.

4. Fully automatic level control.

The coal-fired boiler system has a high automation level, with automatic water adjustment, low water level interlock protection, high and low water level alarms, and other functions.

Complete control and monitoring instruments, convenient maintenance, required operation, and few cares.
