Sawdust pellet steam boiler is a horizontal three-pass water-fire tube hybrid boiler with a bunch of threaded smoke tubes arranged in the drum. The industrial wood pellet boiler furnace is equipped with two sides of the light tube water cooling wall. Adopt light chain grate to realize mechanical feeding, equipped with blower, induced draft fan for mechanical ventilation, and equipped with scraper slag machine to realize automatic slag discharge. The boiler heat exchange system is composed of drum, left and right collector box and water wall. The main heating surface has a furnace water wall, and part of drum and convection tube bundle inside the drum.
This series of steam boiler arches are made of refractory concrete. The back arch is low and long, so it burns well. The two-wing flue and side wall bricks are made of refractory sintered bricks. The front and back walls of the boiler are made of universal refractory bricks. The grate has reasonable air distribution, large combustion chamber, and strong coal type applicability. It is suitable for all kinds of bituminous coal or anthracite coal and mixed coal. Burns well. Because the high-temperature flue gas first enters the settling chamber, and then enters the two-wing flue and front smoke box from both sides, the smoke and dust removal effect is good.
Industrial wood pellet boiler combustion equipment for fast grate, combustion equipment in the factory manufacturing installation completed. After transportation to the site directly installed on the foundation. Reasonable structure, compact, low steel consumption. The performance, weight and size of boiler are obviously advanced compared with domestic products with the same capacity. Biomass steam boiler uses gasification combustion technology, set up advanced gasification rotary combustion chamber, built-in swirl secondary air distribution, make fuel combustion more fully.
The biomass fired boiler adopts green and renewable biomass wood pellet fuel, CO2 achieves zero emission, and the smoke and dust emission concentration is less than 50mg/m3. The smoke density is less than Ringelmann I, and all indicators have reached the national first-class regional environmental protection standards. This series of boilers use high-standard, high-quality auxiliary machinery, accessories and automatic control equipment to ensure the safe and stable operation of the boiler. DZL series steam boilers have simple water circulation and reasonable structure of pressure parts. Under the condition of ensuring water quality, they can operate safely.
Biomass fired boiler has a wide range of fuel sources and is a renewable green energy source. It contains almost no sulfur and low ash content, and its growth process can absorb CO2 generated during the combustion process to achieve zero CO2 emissions. Biomass energy will gradually replace coal and become one of the important energy sources. Biomass fuel includes straw, wood branches, bamboo and wood processing waste, grain shells, fruit shells, sugar residue, oil residue, etc. According to its external dimensions, it can be divided into three types: chips (≤3mm), flakes (≤50mm), and blocks (>50mm).
Industrial wood pellet boiler fuel cost is low, greatly reduce operating costs. Our company can provide users with products of superior value by individually designing for different biomass fuel requirements. At the same time, the lower part of the boiler drum because of the arrangement of the rising pipe row, eliminate the dead water area at the bottom of the drum, so that the sludge is not easy to deposit, the high temperature area of the drum can get superior cooling, to prevent the drum lower bulge.
