DZL type biomass boiler is a single drum longitudinal chain grate boiler using biomass particles as fuel, is a new generation of high efficiency and energy saving boiler products. It uses fuel biomass is an ideal renewable energy, there is a large amount of output every year, using it to replace coal combustion, not only can reduce costs for enterprises, bring rich economic returns, and waste utilization, increase farmers’ income, realize the common development of economic benefits and social benefits. Environmental protection steam boiler also has the advantages of fast pressure boost, high thermal efficiency and large heating area.
Biomass fired boiler is a horizontal three return water and fire tube boiler, the design of the use of high efficiency and energy saving enhanced combustion technology, to ensure the full combustion of fuel. The volume of boiler furnace and ember chamber before biomass is very large, which is conducive to the burning and settling of fly ash. The turning room with coarse separation of dust is set in the outlet smoke window, which achieves the purpose of dust removal in the boiler, reduces the emission of flue gas, and makes it reach the target of environmental protection regulations.
DZL series boiler adopts threaded smoke tube heat transfer, improve thermal efficiency, reduce the application of energy consumption membrane water wall structure, improve the heat transfer coefficient and heat transfer effect, reduce the heat loss. Environmental protection steam boiler thread smoke tube is arranged in the pot shell, the overall air leakage, smoke heat loss is small. Advanced automatic submerged arc welding technology is adopted to ensure the welding quality. This series of steam boiler tail flue is arranged with dust collector, to ensure that the smoke emission meets the environmental requirements. High automation level, with automatic water regulation, low water level interlock protection, high “low water level alarm and other functions. Boiler adopts advanced arch design, forming obvious inverted “A” flame, conducive to the combustion of inferior coal, coal adaptability.
Biomass particle steam boiler control monitoring instrument is complete, boiler operation is safe and reliable. The boiler two wing flue is set, so that the flue gas can enter the front smoke box smoothly, so that the tube plate temperature is the same before, avoid the tube plate crack due to temperature stress. DZL series steam boiler grate adopts a new type of small scale grate, increasing the unique safety ring, so that the grate operation is stable and reliable, improve the combustion efficiency. Biomass pellet fuel contains higher volatile content, ignition temperature, combustion time is long, enhanced combustion furnace temperature is high.
Environmental protection steam boiler using quick installation or assembly factory, convenient installation, shorten the installation cycle. Boiler rear equipped with multi – pipe dust collector, bag dust collector, flue gas emissions better than the specified standard, in line with environmental requirements. Biomass fired steam boiler commonly used pressure gauge for spring pressure gauge, simple structure, accurate and reliable, installation and use is also very convenient. Each biomass steam boiler must be equipped with a pressure gauge directly connected with the steam space of the drum, generally two parallel Settings should be convenient for mutual verification. The pressure gauge must be checked at least once every six months after installation, and the date of check must be marked.
