Recently, the 36-ton circulating fluidized bed (CFB) boiler tailor-made by Huatai Co., Ltd. for a heating enterprise has successfully completed installation and commissioning, achieved successful ignition on the first attempt, and been officially put into operation!

Project Overview: Customized Solution

The heating enterprise, responsible for heating supply in a regional area, adopted a clean heating route at the initial planning stage. Faced with large-scale heating demand and stringent environmental requirements, after multiple rounds of technical comparison and selection, the enterprise chose Huatai’s DHX-series 36-ton CFB boiler as the core heating equipment.

Project Parameters Model: DHX36-1.6-AⅡ Rated evaporation capacity: 36 t/h Rated steam pressure: 1.6 MPa Applicable fuel: Coal

The implementation of this project verifies the reliability and applicability of the DHX-series boilers for large-scale centralized heating projects in Northwest China.

Core Technologies for Stable Heat Source

Why has Huatai’s DHX-series CFB boiler won recognition from heating enterprises? It owes to the comprehensive strengths of the product in efficiency, reliability and environmental performance.

1. Steady-state design for low-bed-pressure operation Steady-state design is adopted according to fuel characteristics to realize low-bed-pressure operation, greatly boosting boiler thermal efficiency. Meanwhile, the pressure of primary air is reduced, cutting fuel and power consumption significantly compared with conventional CFB boilers.

2. Optimized air caps for efficient combustion Adopting improved wear-resistant, low-resistance, anti-ash-leakage, easy-to-replace and anti-falling high-efficiency oxygen-supplying air caps, which ensure uniform fluidization of materials, stable boiler operation and greatly extended service cycle.

3. On-demand air supply and low-temperature staged combustion Low-temperature staged combustion technology rationally distributes the volume of primary and secondary air and delivers secondary air in stages based on fuel features. Independent adjustment enables oxygen supply on demand, creating a strong reducing atmosphere in the lower furnace, effectively curbing the generation of sulfides, nitrogen oxides and other pollutants and lowering initial emission concentration.

4. Patented core technology against wear and ash deposition With patented core technology, the structure of the furnace and rear heating surfaces and material selection are optimized. The boiler features advantages of coal and power saving, high reliability and low pollutant emission. It addresses common drawbacks of traditional CFB boilers including insufficient reliability, poor economy and unsatisfactory environmental performance, especially the pain points of wear, corrosion and ash accumulation.

Lean Construction Ensures First-Time Successful Ignition

From equipment manufacturing to on-site installation, Huatai’s team adheres to the service philosophy of “high quality and high efficiency”. Project managers stayed on-site throughout the process. Upon startup of the intelligent control system, the boiler was ignited smoothly with all operating parameters stable, marking the successful first ignition of the 36-ton CFB boiler.

The successful application of this heating project is an epitome of Huatai’s CFB boilers in the Northwest heating market. From the Beijing-Tianjin-Hebei region to Northeast and Northwest China, Huatai’s heating projects have been launched in many cities, supplying clean heat sources for regional centralized heating, industrial park heating and large commercial complexes. The stable operation of each project serves as a test of Huatai’s product performance, engineering quality and after-sales service capacity.

As clean heating renovation moves forward, demand for reliable thermal equipment keeps rising. Huatai Co., Ltd. will continue to focus on improving product performance and service capacity, supporting the green upgrading of heating systems for more cities, and jointly delivering warm winters and blue skies.
