DZL series of fire tube boiler profile

The new DZL series water and fire tube boiler adopts a series of new technologies and new processes such as threaded tobacco pipe, arched tube plate, airfoil flue, self-support, backwater injection (hot water boiler) and so on, which often appear on the elimination of old DZL series boilers Shell blisters, tube board cracking, water wall tube burst and other ills, the series of boilers to achieve environmental protection, energy efficient, full output and other advantages.

The high temperature flue gas generated on the grate by the fuel is sprayed out between the front and back arches, turned from the hearth to the back, into the airfoil, then turned inside the front smoke box, into the threaded smoke pipe, (Hot water boiler does not deserve), after the dust collector, induced draft fan into the chimney discharge.

Air flows from the blower through the underground air duct into the bunker on both sides of the chain grate, and then enters the separate plenum arranged under the grate from the bunker and supplies the air required for combustion through the vents on the grate.

Assembled steam, hot water boiler (the upper part of the large and base were shipped, the front and rear arches live site. Capacity: 6-12t / h).

DZL series of fire and water boiler structure characteristics

DZL series of boiler assembly consists of the boiler body, chain grate, furnace wall, furnace clothing, platform escalator, before and after the smoke box, economizer (hot water boiler does not deserve), pipe valve and other major components. The difference between a boiler and a quick boiler is that:

1. Due to transport conditions (height, width, weight and other dimensions) restrictions. The main boiler is divided into two parts, the upper part of the factory and the base of the factory, the lower furnace wall (mainly including the front arch, rear arch) site masonry, see below:

2. Hot water boiler water flow changes are as follows: Boiler backwater into the boiler after the first through the backwater jet through the front and rear of the four descending pipe into the lower header, arranged on both sides of the furnace water wall and the siege airfoil flue The convection tube bundle heats into the drum, further heated by the threaded tobacco pipe arranged in the drum tube, and finally supplies the heat user via the outlet valve.
