  • Boiler introduction

The chain grate boiler is a horizontal three return water and fire tube mixing boiler, a bunch of threaded smoke pipe is arranged in the boiler barrel.This type of industrial hot water heater cost low money 

The right and left sides of the furnace is provided with light pipe water cooling wall. The light chain grate is used to realize the mechanical coal feeding, equipped with blower, induced draft fan for mechanical ventilation and the scraper type slag remover machine is used to realize the automatic slag removal. This type of industrial hot water heater cost low money

A new type of energy saving technology is adopted for the front and rear arch of the furnace. The fuel from the coal scuttle fall on the grate grate, into the furnace combustion, the flame passes through the rear arch to refract upward to the front smoke box, then back into the pot tube bundle, after the smoke box into the economizer, and then induced by the draught fan through the flue to the chimney to the atmosphere.

  • Structural characteristics

1. The arched tube plate and thread smoke tube composing of drum, realizing the drum from quasi rigid body into a quasi elastic structure, canceled braces tube plate area, reducing the stress. The tube plate inner smoke pipe by two return to single return, solving the problem of tube plate crack.

2. The lower part of the drum is provided with an upward tube row, the dead water area at the bottom of the boiler barrel is eliminated, so that the slag is not easy to deposit. The high temperature area of the drum can be well cooled, the lower part of the boiler drum is prevented from being wrapped.

3. Heat transfer efficiency of the boiler is improved by using the heat transfer tube with high efficiency, which can enhance the heat transfer effect.This type of industrial hot water heater cost low money

4. Compact structure, compared with the same type of boiler, the size of small size, saving boiler room infrastructure investment.

5. Stable operation, easy adjustment, sufficient output.

6. The flue gas has a disturbance in the pipe, so the dust is not easy to accumulate in the smoke pipe.

7. The character of the wall, exit part has certain dust effect, the original dust concentration of the boiler is controlled below the standard, so as to ensure that the soot emission of the boiler reaches the national environmental protection standards.

8. Double two wind unique design, improve the coal fuel fire conditions, the independent air chamber making a reasonable air distribution, forming a favorable aerodynamic field in the furnace, realizing high temperature, high combustion efficiency.
