What is the combustion mode of coal/biomass fired boilers?

The combustion mode of coal/biomass boiler is stratified combustion. The flue is placed on a fixed or moving grate to form a uniform fuel bed with a certain thickness, and the air comes out from the bottom of the grate and combustion occurs on the fuel bed.

What is the thickness of the refractory?

Thickness of refractory: 50-60 mm.

What is the installation sequence?

Boiler - economizer - Dust collector -ID fan - chimney.

AI-Powered supplier vetting

SummaryLeineng Boiler (Henan) Co., Ltd. is a China-based trading company established in 2023 with 10 employees. It offers various boilers and reverse osmosis water treatment equipment, and its registered business scope includes special equipment manufacturing, installation, renovation, and repair subject to approval. The company states that it applies standardized management and an ISO9000 quality management system, but no specific certification document is provided. It reports product and after-sales service guarantees and offers sample-based and full customization. However, the supplier has no available SDK, only one year of stated R&D engineer experience, and its environmental, fire-drill, and environmental-approval statuses are unknown. Financial records are identified by year, but no substantive financial results are provided. An SGS audit record exists, although the evaluation result is recorded as 0 and the audit type is not explained.

Supplier typeThe supplier is identified consistently as a trading company and a limited company based in Zhengzhou, Henan, China. Its stated scope includes sales of boilers and related equipment, while its licensed scope also covers special equipment manufacturing, installation, renovation, and repair subject to legal approval.

After-Sales capabilityThe supplier explicitly describes after-sales service as institutionalized and standardized and claims reliable guarantees for product quality and after-sales service. It also states a quality objective of zero complaints, but no service staffing, response-time, warranty, or completed service-case evidence is provided.

R&D capabilityThe supplier lists mechanical equipment research and development and industrial engineering design services in its business scope, but it reports no available SDK and only one year of total R&D engineer experience. These records do not demonstrate strong innovation capability.

Customization capabilityThe supplier explicitly offers customization from samples and full customization, which directly supports project-specific design flexibility. No further information is provided on technical resources, lead times, or customization limits.

Product Q&A

Q:What are the spare parts of DZL/SZL series coal/biomass boilers?

Usually, spare parts are instrument valves, grate plates, gaskets, etc.

Q:What is the difference between DZL and SZL of the same capacity?

DZL: Usually used for boilers with a capacity of less than 10 tons, easy to transport, low requirements for water quality, and low boiler room construction charges. SZL: Suitable for larger capacity boilers, good water circulation, small water volume, faster preheating, higher steam quality, higher requirements for water quality, and higher thermal efficiency.

Q:What is the difference between vertical boiler and horizontal boiler with the same capacity?

Vertical boiler: Compact structure, limited floor space, easy installation and disassembly, low cost of capital construction, less investment, rapid and abundant steam consumption. Horizontal boiler: Large combustion space, higher thermal efficiency than vertical boiler, less heat loss, stronger output, and higher steam quality.

Q:What are the limitations (size, humidity, chemical concentration) of coal/solid/wood fuels?

Coal size: 6-25 mm. Coal blending size: <50 mm (less than 6 mm coal should be less than 30%). Biomass particle diameter: 6 ~ 10 mm, length: 25 ~ 50 mm, water content <15%, ash <2%, sulfur content <0.07%, chlorine <0.07%, nitrogen <0.5%.

Q:What are the dimensions of the furnace door and blower hopper?

Door size: Standard oval furnace door: 300*800*1500. Blower hopper size: 2 tons conical hopper: 1400*800*1500; 4 tons cone hopper: 2200*1400*1500.
